CVE-2025-38427 (GCVE-0-2025-38427)
Vulnerability from cvelistv5 – Published: 2025-07-25 14:16 – Updated: 2025-07-28 04:21
VLAI?
EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
video: screen_info: Relocate framebuffers behind PCI bridges
Apply PCI host-bridge window offsets to screen_info framebuffers. Fixes
invalid access to I/O memory.
Resources behind a PCI host bridge can be relocated by a certain offset
in the kernel's CPU address range used for I/O. The framebuffer memory
range stored in screen_info refers to the CPU addresses as seen during
boot (where the offset is 0). During boot up, firmware may assign a
different memory offset to the PCI host bridge and thereby relocating
the framebuffer address of the PCI graphics device as seen by the kernel.
The information in screen_info must be updated as well.
The helper pcibios_bus_to_resource() performs the relocation of the
screen_info's framebuffer resource (given in PCI bus addresses). The
result matches the I/O-memory resource of the PCI graphics device (given
in CPU addresses). As before, we store away the information necessary to
later update the information in screen_info itself.
Commit 78aa89d1dfba ("firmware/sysfb: Update screen_info for relocated
EFI framebuffers") added the code for updating screen_info. It is based
on similar functionality that pre-existed in efifb. Efifb uses a pointer
to the PCI resource, while the newer code does a memcpy of the region.
Hence efifb sees any updates to the PCI resource and avoids the issue.
v3:
- Only use struct pci_bus_region for PCI bus addresses (Bjorn)
- Clarify address semantics in commit messages and comments (Bjorn)
v2:
- Fixed tags (Takashi, Ivan)
- Updated information on efifb

generic RX path where multiple sockets share
single xsk_buff_pool.
RX queue is exclusive to xsk_socket, while FILL
queue can be shared between multiple sockets.
This could result in race condition where two
CPU cores access RX path of two different sockets
sharing the same umem.
Protect both queues by acquiring spinlock in shared
xsk_buff_pool.
Lock contention may be minimized in the future by some
per-thread FQ buffering.
It's safe and necessary to move spin_lock_bh(rx_lock)
after xsk_rcv_check():
* xs->pool and spinlock_init is synchronized by
xsk_bind() -> xsk_is_bound() memory barriers.
* xsk_rcv_check() may return true at the moment
of xsk_release() or xsk_unbind_dev(),
however this will not cause any data races or
race conditions. xsk_unbind_dev() removes xdp
socket from all maps and waits for completion
of all outstanding rx operations. Packets in
RX path will either complete safely or drop.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bus: fsl-mc: fix double-free on mc_dev
The blamed commit tried to simplify how the deallocations are done but,
in the process, introduced a double-free on the mc_dev variable.
In case the MC device is a DPRC, a new mc_bus is allocated and the
mc_dev variable is just a reference to one of its fields. In this
circumstance, on the error path only the mc_bus should be freed.
This commit introduces back the following checkpatch warning which is a
false-positive.
WARNING: kfree(NULL) is safe and this check is probably not required
+ if (mc_bus)
+ kfree(mc_bus);

This issue happens when the file descriptor is closed before the jobs
submitted by it are completed. When the job completes, we update the
global GPU stats and the per-fd GPU stats, which are exposed through
fdinfo. If the file descriptor was closed, then the struct `v3d_file_priv`
and its stats were already freed and we can't update the per-fd stats.
Therefore, if the file descriptor was already closed, don't u

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: lan743x: fix potential out-of-bounds write in lan743x_ptp_io_event_clock_get()
Before calling lan743x_ptp_io_event_clock_get(), the 'channel' value
is checked against the maximum value of PCI11X1X_PTP_IO_MAX_CHANNELS(8).
This seems correct and aligns with the PTP interrupt status register
(PTP_INT_STS) specifications.
However, lan743x_ptp_io_event_clock_get() writes to ptp->extts[] with
only LAN743X_PTP_N_EXTTS(4) elements, using channel as an index:
lan743x_ptp_io_event_clock_get(..., u8 channel,...)
{
...
/* Update Local timestamp */
extts = &ptp->extts[channel];
extts->ts.tv_sec = sec;
...
}
To avoid an out-of-bounds write and utilize all the supported GPIO
inputs, set LAN743X_PTP_N_EXTTS to 8.
Detected using the static analysis tool - Svace.

CVE-2025-37885 (GCVE-0-2025-37885)
Vulnerability from cvelistv5 – Published: 2025-05-09 06:45 – Updated: 2025-11-03 19:56

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Reset IRTE to host control if *new* route isn't postable
Restore an IRTE back to host control (remapped or posted MSI mode) if the
*new* GSI route prevents posting the IRQ directly to a vCPU, regardless of
the GSI routing type. Updating the IRTE if and only if the new GSI is an
MSI results in KVM leaving an IRTE posting to a vCPU.
The dangling IRTE can result in interrupts being incorrectly delivered to
the guest, and in the worst case scenario can result in use-after-free,
e.g. if the VM is torn down, but the underlying host IRQ isn't freed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix GCC_GCC_PCIE_HOT_RST definition for WCN7850
GCC_GCC_PCIE_HOT_RST is wrongly defined for WCN7850, causing kernel crash
on some specific platforms.
Since this register is divergent for WCN7850 and QCN9274, move it to
register table to allow different definitions. Then correct the register
address for WCN7850 to fix this issue.
Note IPQ5332 is not affected as it is not PCIe based device.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3

CVE-2025-38391 (GCVE-0-2025-38391)
Vulnerability from cvelistv5 – Published: 2025-07-25 12:53 – Updated: 2025-11-03 17:37

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: altmodes/displayport: do not index invalid pin_assignments
A poorly implemented DisplayPort Alt Mode port partner can indicate
that its pin assignment capabilities are greater than the maximum
value, DP_PIN_ASSIGN_F. In this case, calls to pin_assignment_show
will cause a BRK exception due to an out of bounds array access.
Prevent for loop in pin_assignment_show from accessing
invalid values in pin_assignments by adding DP_PIN_ASSIGN_MAX
value in typec_dp.h and using i < DP_PIN_ASSIGN_MAX as a loop
condition.
Severity ?

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: cxusb: no longer judge rbuf when the write fails
syzbot reported a uninit-value in cxusb_i2c_xfer. [1]
Only when the write operation of usb_bulk_msg() in dvb_usb_generic_rw()
succeeds and rlen is greater than 0, the read operation of usb_bulk_msg()
will be executed to read rlen bytes of data from the dvb device into the
rbuf.
In this case, although rlen is 1, the write operation failed which resulted
in the dvb read operation not being executed, and ultimately variable i was
not initialized.

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
__legitimize_mnt(): check for MNT_SYNC_UMOUNT should be under mount_lock
... or we risk stealing final mntput from sync umount - raising mnt_count
after umount(2) has verified that victim is not busy, but before it
has set MNT_SYNC_UMOUNT; in that case __legitimize_mnt() doesn't see
that it's safe to quietly undo mnt_count increment and leaves dropping
the reference to caller, where it'll be a full-blown mntput().
Check under mount_lock is needed; leaving the current one done before
taking that makes no sense - it's nowhere near common enough to bother
with.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btintel: Check dsbr size from EFI variable
Since the size of struct btintel_dsbr is already known, we can just
start there instead of querying the EFI variable size. If the final
result doesn't match what we expect also fail. This fixes a stack buffer
overflow when the EFI variable is larger than struct btintel_dsbr.
Severity ?
No CVSS data available.

CVE-2025-38257 (GCVE-0-2025-38257)

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/pkey: Prevent overflow in size calculation for memdup_user()
Number of apqn target list entries contained in 'nr_apqns' variable is
determined by userspace via an ioctl call so the result of the product in
calculation of size passed to memdup_user() may overflow.
In this case the actual size of the allocated area and the value
describing it won't be in sync leading to various types of unpredictable
behaviour later.
Use a proper memdup_array_user() helper which returns an error if an
overflow is detected. Note that it is different from when nr_apqns is
initially zero - that case is considered valid and should be handled in
subsequent pkey_handler implementations.
Found by Linux Verification Center (linuxtesting.org).

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/xe/guc: Explicitly exit CT safe mode on unwind
During driver probe we might be briefly using CT safe mode, which
is based on a delayed work, but usually we are able to stop this
once we have IRQ fully operational. However, if we abort the probe
quite early then during unwind we might try to destroy the workqueue
while there is still a pending delayed work that attempts to restart
itself which triggers a WARN.
This was recently observed during unsuccessful VF initialization:
[ ] xe 0000:00:02.1: probe with driver xe failed with error -62
[ ] ------------[ cut here ]------------
[ ] workqueue: cannot queue safe_mode_worker_func [xe] on wq xe-g2h-wq
[ ] WARNING: CPU: 9 PID: 0 at kernel/workqueue.c:2257 __queue_work+0x287/0x710
[ ] RIP: 0010:__queue_work+0x287/0x710
[ ] Call Trace:
[ ] delayed_work_timer_fn+0x19/0x30
[ ] call_timer_fn+0xa1/0x2a0
Exit the CT safe mode on unwind to avoid that warning.

CVE-2025-38035 (GCVE-0-2025-38035)

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvmet-tcp: don't restore null sk_state_change
queue->state_change is set as part of nvmet_tcp_set_queue_sock(), but if
the TCP connection isn't established when nvmet_tcp_set_queue_sock() is
called then queue->state_change isn't set and sock->sk->sk_state_change
isn't replaced.
As such we don't need to restore sock->sk->sk_state_change if
queue->state_change is NULL.
This avoids NULL pointer dereferences such as this:

CVE-2025-38107 (GCVE-0-2025-38107)
Vulnerability from cvelistv5 – Published: 2025-07-03 08:35 – Updated: 2025-11-03 17:34

Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: ets: fix a race in ets_qdisc_change()
Gerrard Tai reported a race condition in ETS, whenever SFQ perturb timer
fires at the wrong time.
The race is as follows:
CPU 0 CPU 1
[1]: lock root
[2]: qdisc_tree_flush_backlog()
[3]: unlock root
|
| [5]: lock root
| [6]: rehash
| [7]: qdisc_tree_reduce_backlog()
|
[4]: qdisc_put()
This can be abused to underflow a parent's qlen.
Calling qdisc_purge_queue() instead of qdisc_tree_flush_backlog()
should fix the race, because all packets will be purged from the qdisc
before releasing the lock.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: Return NULL when htb_lookup_leaf encounters an empty rbtree
htb_lookup_leaf has a BUG_ON that can trigger with the following:
tc qdisc del dev lo root
tc qdisc add dev lo root handle 1: htb default 1
tc class add dev lo parent 1: classid 1:1 htb rate 64bit
tc qdisc add dev lo parent 1:1 handle 2: netem
tc qdisc add dev lo parent 2:1 handle 3: blackhole
ping -I lo -c1 -W0.001 127.0.0.1
The root cause is the following:
1. htb_dequeue calls htb_dequeue_tree which calls the dequeue handler on
the selected leaf qdisc
2. netem_dequeue calls enqueue on the child qdisc
3. blackhole_enqueue drops the packet and returns a value that is not
just NET_XMIT_SUCCESS
4. Because of this, netem_dequeue calls qdisc_tree_reduce_backlog, and
since qlen is now 0, it calls htb_qlen_notify -> htb_deactivate ->
htb_deactiviate_prios -> htb_remove_class_from_row -> htb_safe_rb_erase
5. As this is the only class in the selected hprio rbtree,
__rb_change_child in __rb_erase_augmented sets the rb_root pointer to
NULL
6. Because blackhole_dequeue returns NULL, netem_dequeue returns NULL,
which causes htb_dequeue_tree to call htb_lookup_leaf with the same
hprio rbtree, and fail the BUG_ON
The function graph for this scenario is shown here:
0) | htb_enqueue() {
0) + 13.635 us | netem_enqueue();
0) 4.719 us | htb_activate_prios();
0) # 2249.199 us | }
0) | htb_dequeue() {
0) 2.355 us | htb_lookup_leaf();
0) | netem_dequeue() {
0) + 11.061 us | blackhole_enqueue();
0) | qdisc_tree_reduce_backlog() {
0) | qdisc_lookup_rcu() {
0) 1.873 us | qdisc_match_from_root();
0) 6.292 us | }
0) 1.894 us | htb_search();
0) | htb_qlen_notify() {
0) 2.655 us | htb_deactivate_prios();
0) 6.933 us | }
0) + 25.227 us | }
0) 1.983 us | blackhole_dequeue();
0) + 86.553 us | }
0) # 2932.761 us | qdisc_warn_nonwc();
0) | htb_lookup_leaf() {
0) | BUG_ON();
------------------------------------------
The full original bug report can be seen here [1].
We can fix this just by returning NULL instead of the BUG_ON,
as htb_dequeue_tree returns NULL when htb_lookup_leaf returns
NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mdiobus: Fix potential out-of-bounds clause 45 read/write access
When using publicly available tools like 'mdio-tools' to read/write data
from/to network interface and its PHY via C45 (clause 45) mdiobus,
there is no verification of parameters passed to the ioctl and
it accepts any mdio address.
Currently there is support for 32 addresses in kernel via PHY_MAX_ADDR define,
but it is possible to pass higher value than that via ioctl.
While read/write operation should generally fail in this case,
mdiobus provides stats array, where wrong address may allow out-of-bounds
read/write.
Fix that by adding address verification before C45 read/write operation.
While this excludes this access from any statistics, it improves security of
read/write operation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/a7xx: Call CP_RESET_CONTEXT_STATE
Calling this packet is necessary when we switch contexts because there
are various pieces of state used by userspace to synchronize between BR
and BV that are persistent across submits and we need to make sure that
they are in a "safe" state when switching contexts. Otherwise a
userspace submission in one context could cause another context to
function incorrectly and hang, effectively a denial of service (although
without leaking data). This was missed during initial a7xx bringup.

Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio: break and reset virtio devices on device_shutdown()
Hongyu reported a hang on kexec in a VM. QEMU reported invalid memory
accesses during the hang.
Invalid read at addr 0x102877002, size 2, region '(null)', reason: rejected
Invalid write at addr 0x102877A44, size 2, region '(null)', reason: rejected
...
It was traced down to virtio-console. Kexec works fine if virtio-console
is not in use.
The issue is that virtio-console continues to write to the MMIO even after
underlying virtio-pci device is reset.
Additionally, Eric noticed that IOMMUs are reset before devices, if
devices are not reset on shutdown they continue to poke at guest memory
and get errors from the IOMMU. Some devices get wedged then.
The problem can be solved by breaking all virtio devices on virtio
bus shutdown, then resetting them.
Severity ?

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Don't leave consecutive consumed OOB skbs.
Jann Horn reported a use-after-free in unix_stream_read_generic().
The following sequences reproduce the issue:
$ python3
from socket import *
s1, s2 = socketpair(AF_UNIX, SOCK_STREAM)
s1.send(b'x', MSG_OOB)
s2.recv(1, MSG_OOB) # leave a consumed OOB skb
s1.send(b'y', MSG_OOB)
s2.recv(1, MSG_OOB) # leave a consumed OOB skb
s1.send(b'z', MSG_OOB)
s2.recv(1) # recv 'z' illegally
s2.recv(1, MSG_OOB) # access 'z' skb (use-after-free)
Even though a user reads OOB data, the skb holding the data stays on
the recv queue to mark the OOB boundary and break the next recv().
After the last send() in the scenario above, the sk2's recv queue has
2 leading consumed OOB skbs and 1 real OOB skb.
Then, the following happens during the next recv() without MSG_OOB
1. unix_stream_read_generic() peeks the first consumed OOB skb
2. manage_oob() returns the next consumed OOB skb
3. unix_stream_read_generic() fetches the next not-yet-consumed OOB skb
4. unix_stream_read_generic() reads and frees the OOB skb
, and the last recv(MSG_OOB) triggers KASAN splat.
The 3. above occurs because of the SO_PEEK_OFF code, which does not
expect unix_skb_len(skb) to be 0, but this is true for such consumed
OOB skbs.
while (skip >= unix_skb_len(skb)) {
skip -= unix_skb_len(skb);
skb = skb_peek_next(skb, &sk->sk_receive_queue);
...
}
In addition to this use-after-free, there is another issue that
ioctl(SIOCATMARK) does not function properly with consecutive consumed
OOB skbs.
So, nothing good comes out of such a situation.
Instead of complicating manage_oob(), ioctl() handling, and the next
ECONNRESET fix by introducing a loop for consecutive consumed OOB skbs,
let's not leave such consecutive OOB unnecessarily.
Now, while receiving an OOB skb in unix_stream_recv_urg(), if its
previous skb is a consumed OOB skb, it is freed.

CVE-2025-38386 (GCVE-0-2025-38386)

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPICA: Refuse to evaluate a method if arguments are missing
As reported in [1], a platform firmware update that increased the number
of method parameters and forgot to update a least one of its callers,
caused ACPICA to crash due to use-after-free.
Since this a result of a clear AML issue that arguably cannot be fixed
up by the interpreter (it cannot produce missing data out of thin air),
address it by making ACPICA refuse to evaluate a method if the caller
attempts to pass fewer arguments than expected to it.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring/rsrc: fix folio unpinning
syzbot complains about an unmapping failure:

We can pin a tail page of a folio, but then io_uring will try to unpin
the head page of the folio. While it should be fine in terms of keeping
the page actually alive, mm folks say it's wrong and triggers a debug
warning. Use unpin_user_folio() instead of unpin_user_page*.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: core: ensure the allocated report buffer can contain the reserved report ID
When the report ID is not used, the low level transport drivers expect
the first byte to be 0. However, currently the allocated buffer not
account for that extra byte, meaning that instead of having 8 guaranteed
bytes for implement to be working, we only have 7.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: Fix fb_set_var to prevent null-ptr-deref in fb_videomode_to_var
If fb_add_videomode() in fb_set_var() fails to allocate memory for
fb_videomode, later it may lead to a null-ptr dereference in
fb_videomode_to_var(), as the fb_info is registered while not having the
mode in modelist that is expected to be there, i.e. the one that is
described in fb_info->var.
================================================================
general protection fault, probably for non-canonical address 0xdffffc0000000001: 0000 [#1] PREEMPT SMP KASAN NOPTI
KASAN: null-ptr-deref in range [0x0000000000000008-0x000000000000000f]

================================================================
The reason is that fb_info->var is being modified in fb_set_var(), and
then fb_videomode_to_var() is called. If it fails to add the mode to
fb_info->modelist, fb_set_var() returns error, but does not restore the
old value of fb_info->var. Restore fb_info->var on failure the same way
it is done earlier in the function.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath6kl: remove WARN on bad firmware input
If the firmware gives bad input, that's nothing to do with
the driver's stack at this point etc., so the WARN_ON()
doesn't add any value. Additionally, this is one of the
top syzbot reports now. Just print a message, and as an
added bonus, print the sizes too.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: fix eswitch code memory leak in reset scenario
Add simple eswitch mode checker in attaching VF procedure and allocate
required port representor memory structures only in switchdev mode.
The reset flows triggers VF (if present) detach/attach procedure.
It might involve VF port representor(s) re-creation if the device is
configured is switchdev mode (not legacy one).
The memory was blindly allocated in current implementation,
regardless of the mode and not freed if in legacy mode.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix helper writes to read-only maps
Lonial found an issue that despite user- and BPF-side frozen BPF map
(like in case of .rodata), it was still possible to write into it from
a BPF program side through specific helpers having ARG_PTR_TO_{LONG,INT}
as arguments.
In check_func_arg() when the argument is as mentioned, the meta->raw_mode
is never set. Later, check_helper_mem_access(), under the case of
PTR_TO_MAP_VALUE as register base type, it assumes BPF_READ for the
subsequent call to check_map_access_type() and given the BPF map is
read-only it succeeds.
The helpers really need to be annotated as ARG_PTR_TO_{LONG,INT} | MEM_UNINIT
when results are written into them as opposed to read out of them. The
latter indicates that it's okay to pass a pointer to uninitialized memory
as the memory is written to anyway.
However, ARG_PTR_TO_{LONG,INT} is a special case of ARG_PTR_TO_FIXED_SIZE_MEM
just with additional alignment requirement. So it is better to just get
rid of the ARG_PTR_TO_{LONG,INT} special cases altogether and reuse the
fixed size memory types. For this, add MEM_ALIGNED to additionally ensure
alignment given these helpers write directly into the args via *<ptr> = val.
The .arg*_size has been initialized reflecting the actual sizeof(*<ptr>).
MEM_ALIGNED can only be used in combination with MEM_FIXED_SIZE annotated
argument types, since in !MEM_FIXED_SIZE cases the verifier does not know
the buffer size a priori and therefore cannot blindly write *<ptr> = val.
Severity ?

Summary
In the Linux kernel, the following vulnerability has been resolved:
software node: Correct a OOB check in software_node_get_reference_args()
software_node_get_reference_args() wants to get @index-th element, so
the property value requires at least '(index + 1) * sizeof(*ref)' bytes
but that can not be guaranteed by current OOB check, and may cause OOB
for malformed property.
Fix by using as OOB check '((index + 1) * sizeof(*ref) > prop->length)'.
Severity ?

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: target: Fix NULL pointer dereference in core_scsi3_decode_spec_i_port()
The function core_scsi3_decode_spec_i_port(), in its error code path,
unconditionally calls core_scsi3_lunacl_undepend_item() passing the
dest_se_deve pointer, which may be NULL.
This can lead to a NULL pointer dereference if dest_se_deve remains
unset.
SPC-3 PR SPEC_I_PT: Unable to locate dest_tpg
Unable to handle kernel paging request at virtual address dfff800000000012
Call trace:
core_scsi3_lunacl_undepend_item+0x2c/0xf0 [target_core_mod] (P)
core_scsi3_decode_spec_i_port+0x120c/0x1c30 [target_core_mod]
core_scsi3_emulate_pro_register+0x6b8/0xcd8 [target_core_mod]
target_scsi3_emulate_pr_out+0x56c/0x840 [target_core_mod]
Fix this by adding a NULL check before calling
core_scsi3_lunacl_undepend_item()

Lion's patch [1] revealed an ancient bug in the qdisc API.
Whenever a user creates/modifies a qdisc specifying as a parent another
qdisc, the qdisc API will, during grafting, detect that the user is
not trying to attach to a class and reject. However grafting is
performed after qdisc_create (and thus the qdiscs' init callback) is
executed. In qdiscs that eventually call qdisc_tree_reduce_backlog
during init or change (such as fq, hhf, choke, etc), an issue
arises. For example, executing the following commands:
sudo tc qdisc add dev lo root handle a: htb default 2
sudo tc qdisc add dev lo parent a: handle beef fq
Qdiscs such as fq, hhf, choke, etc unconditionally invoke
qdisc_tree_reduce_backlog() in their control path init() or change() which
then causes a failure to find the child class; however, that does not stop
the unconditional invocation of the assumed child qdisc's qlen_notify with
a null class. All these qdiscs make the assumption that class is non-null.
The solution is ensure that qdisc_leaf() which looks up the parent
class, and is invoked prior to qdisc_create(), should return failure on
not finding the class.
In this patch, we leverage qdisc_leaf to return ERR_PTRs whenever the
parentid doesn't correspond to a class, so that we can detect it
earlier on and abort before qdisc_create is called.

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: fix use-after-free in taprio_dev_notifier
Since taprio’s taprio_dev_notifier() isn’t protected by an
RCU read-side critical section, a race with advance_sched()
can lead to a use-after-free.
Adding rcu_read_lock() inside taprio_dev_notifier() prevents this.
Severity ?
No CVSS data available.

After calling bpf_exec_tx_verdict(), the size of msg_pl->sg may increase,
e.g., when the BPF program executes bpf_msg_push_data().
If the BPF program sets cork_bytes and sg.size is smaller than cork_bytes,
it will return -ENOSPC and attempt to roll back to the non-zero copy
logic. However, during rollback, msg->msg_iter is reset, but since
msg_pl->sg.size has been increased, subsequent executions will exceed the
actual size of msg_iter.
'''
iov_iter_revert(&msg->msg_iter, msg_pl->sg.size - orig_size);
'''
The changes in this commit are based on the following considerations:
1. When cork_bytes is set, rolling back to non-zero copy logic is
pointless and can directly go to zero-copy logic.
2. We can not calculate the correct number of bytes to revert msg_iter.
Assume the original data is "abcdefgh" (8 bytes), and after 3 pushes
by the BPF program, it becomes 11-byte data: "abc?de?fgh?".
Then, we set cork_bytes to 6, which means the first 6 bytes have been
processed, and the remaining 5 bytes "?fgh?" will be cached until the
length meets the cork_bytes requirement.
However, some data in "?fgh?" is not within 'sg->msg_iter'
(but in msg_pl instead), especially the data "?" we pushed.
So it doesn't seem as simple as just reverting through an offset of
msg_iter.
3. For non-TLS sockets in tcp_bpf_sendmsg, when a "cork" situation occurs,
the user-space send() doesn't return an error, and the returned length is
the same as the input length parameter, even if some data is cached.
Additionally, I saw that the current non-zero-copy logic for handling
corking is written as:
'''
line 1177
else if (ret != -EAGAIN) {
if (ret == -ENOSPC)
ret = 0;
goto send_end;
'''
So it's ok to just return 'copied' without error when a "cork" situation
occurs.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfs: Clean up /proc/net/rpc/nfs when nfs_fs_proc_net_init() fails.
syzbot reported a warning below [1] following a fault injection in
nfs_fs_proc_net_init(). [0]
When nfs_fs_proc_net_init() fails, /proc/net/rpc/nfs is not removed.
Later, rpc_proc_exit() tries to remove /proc/net/rpc, and the warning
is logged as the directory is not empty.
Let's handle the error of nfs_fs_proc_net_init() properly.
[0]:
FAULT_INJECTION: forcing a failure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (asus-ec-sensors) check sensor index in read_string()
Prevent a potential invalid memory access when the requested sensor
is not found.
find_ec_sensor_index() may return a negative value (e.g. -ENOENT),
but its result was used without checking, which could lead to
undefined behavior when passed to get_sensor_info().
Add a proper check to return -EINVAL if sensor_index is negative.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
[groeck: Return error code returned from find_ec_sensor_index]
Severity ?

nbd_genl_connect() does not properly stop the device on certain
error paths after nbd_start_device() has been called. This causes
the error path to put nbd->config while recv_work continue to use
the config after putting it, leading to use-after-free in recv_work.
This patch moves nbd_start_device() after the backend file creation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: usb: aqc111: fix error handling of usbnet read calls
Syzkaller, courtesy of syzbot, identified an error (see report [1]) in
aqc111 driver, caused by incomplete sanitation of usb read calls'
results. This problem is quite similar to the one fixed in commit
920a9fa27e78 ("net: asix: add proper error handling of usb read errors").
For instance, usbnet_read_cmd() may read fewer than 'size' bytes,
even if the caller expected the full amount, and aqc111_read_cmd()
will not check its result properly. As [1] shows, this may lead
to MAC address in aqc111_bind() being only partly initialized,
triggering KMSAN warnings.
Fix the issue by verifying that the number of bytes read is
as expected and not less.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: only dirty folios when data journaling regular files
fstest generic/388 occasionally reproduces a crash that looks as
follows:
BUG: kernel NULL pointer dereference, address: 0000000000000000
...
Call Trace:
<TASK>
ext4_block_zero_page_range+0x30c/0x380 [ext4]
ext4_truncate+0x436/0x440 [ext4]
ext4_process_orphan+0x5d/0x110 [ext4]

do_syscall_64+0x82/0x170
...
This occurs when processing a symlink inode from the orphan list. The
partial block zeroing code in the truncate path calls
ext4_dirty_journalled_data() -> folio_mark_dirty(). The latter calls
mapping->a_ops->dirty_folio(), but symlink inodes are not assigned an
a_ops vector in ext4, hence the crash.
To avoid this problem, update the ext4_dirty_journalled_data() helper to
only mark the folio dirty on regular files (for which a_ops is
assigned). This also matches the journaling logic in the ext4_symlink()
creation path, where ext4_handle_dirty_metadata() is called directly.
Severity ?

Summary
In the Linux kernel, the following vulnerability has been resolved:
coresight: holding cscfg_csdev_lock while removing cscfg from csdev
There'll be possible race scenario for coresight config:
CPU0 CPU1
(perf enable) load module
cscfg_load_config_sets()
activate config. // sysfs
(sys_active_cnt == 1)
...
cscfg_csdev_enable_active_config()
lock(csdev->cscfg_csdev_lock)
deactivate config // sysfs
(sys_activec_cnt == 0)
cscfg_unload_config_sets()
<iterating config_csdev_list> cscfg_remove_owned_csdev_configs()
// here load config activate by CPU1
unlock(csdev->cscfg_csdev_lock)
iterating config_csdev_list could be raced with config_csdev_list's
entry delete.
To resolve this race , hold csdev->cscfg_csdev_lock() while
cscfg_remove_owned_csdev_configs()

'''
The panic originates from the assertion BUG_ON(skb_shared(skb)) in
skb_linearize(). A previous commit(see Fixes tag) introduced skb_get()
to avoid race conditions between skb operations in the backlog and skb
release in the recvmsg path. However, this caused the panic to always
occur when skb_linearize is executed.
The "--rx-strp 100000" parameter forces the RX path to use the strparser
module which aggregates data until it reaches 100KB before calling sockmap
logic. The 100KB payload exceeds MAX_MSG_FRAGS, triggering skb_linearize.
To fix this issue, just move skb_get into sk_psock_skb_ingress_enqueue.
'''
sk_psock_backlog:
sk_psock_handle_skb
skb_get(skb) <== we move it into 'sk_psock_skb_ingress_enqueue'
sk_psock_skb_ingress____________
↓

| → sk_psock_skb_ingress_self
| sk_psock_skb_ingress_enqueue
sk_psock_verdict_apply_________________↑ skb_linearize

Note that for verdict_apply path, the skb_get operation is unnecessary so
we add 'take_ref' param to control it's behavior.

Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio-net: ensure the received length does not exceed allocated size
In xdp_linearize_page, when reading the following buffers from the ring,
we forget to check the received length with the true allocate size. This
can lead to an out-of-bound read. This commit adds that missing check.
Severity ?
No CVSS data available.

CVE-2025-38109 (GCVE-0-2025-38109)
Vulnerability from cvelistv5 – Published: 2025-07-03 08:35 – Updated: 2025-07-28 04:12

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Fix ECVF vports unload on shutdown flow
Fix shutdown flow UAF when a virtual function is created on the embedded
chip (ECVF) of a BlueField device. In such case the vport acl ingress
table is not properly destroyed.
ECVF functionality is independent of ecpf_vport_exists capability and
thus functions mlx5_eswitch_(enable|disable)_pf_vf_vports() should not
test it when enabling/disabling ECVF vports.
kernel log:
[] refcount_t: underflow; use-after-free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vsock: Fix transport_{g2h,h2g} TOCTOU
vsock_find_cid() and vsock_dev_do_ioctl() may race with module unload.
transport_{g2h,h2g} may become NULL after the NULL check.
Introduce vsock_transport_local_cid() to protect from a potential
null-ptr-deref.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: clear the dst when changing skb protocol
A not-so-careful NAT46 BPF program can crash the kernel
if it indiscriminately flips ingress packets from v4 to v6:
BUG: kernel NULL pointer dereference, address: 0000000000000000
ip6_rcv_core (net/ipv6/ip6_input.c:190:20)
ipv6_rcv (net/ipv6/ip6_input.c:306:8)
process_backlog (net/core/dev.c:6186:4)
napi_poll (net/core/dev.c:6906:9)
net_rx_action (net/core/dev.c:7028:13)
do_softirq (kernel/softirq.c:462:3)
netif_rx (net/core/dev.c:5326:3)
dev_loopback_xmit (net/core/dev.c:4015:2)
ip_mc_finish_output (net/ipv4/ip_output.c:363:8)
NF_HOOK (./include/linux/netfilter.h:314:9)
ip_mc_output (net/ipv4/ip_output.c:400:5)
dst_output (./include/net/dst.h:459:9)
ip_local_out (net/ipv4/ip_output.c:130:9)
ip_send_skb (net/ipv4/ip_output.c:1496:8)
udp_send_skb (net/ipv4/udp.c:1040:8)
udp_sendmsg (net/ipv4/udp.c:1328:10)
The output interface has a 4->6 program attached at ingress.
We try to loop the multicast skb back to the sending socket.
Ingress BPF runs as part of netif_rx(), pushes a valid v6 hdr
and changes skb->protocol to v6. We enter ip6_rcv_core which
tries to use skb_dst(). But the dst is still an IPv4 one left
after IPv4 mcast output.
Clear the dst in all BPF helpers which change the protocol.
Try to preserve metadata dsts, those may carry non-routing
metadata.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
platform/x86: dell_rbu: Fix list usage
Pass the correct list head to list_for_each_entry*() when looping through
the packet list.
Without this patch, reading the packet data via sysfs will show the data
incorrectly (because it starts at the wrong packet), and clearing the
packet list will result in a NULL pointer dereference.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
calipso: Don't call calipso functions for AF_INET sk.
syzkaller reported a null-ptr-deref in txopt_get(). [0]
The offset 0x70 was of struct ipv6_txoptions in struct ipv6_pinfo,
so struct ipv6_pinfo was NULL there.
However, this never happens for IPv6 sockets as inet_sk(sk)->pinet6
is always set in inet6_create(), meaning the socket was not IPv6 one.
The root cause is missing validation in netlbl_conn_setattr().
netlbl_conn_setattr() switches branches based on struct
sockaddr.sa_family, which is passed from userspace. However,
netlbl_conn_setattr() does not check if the address family matches
the socket.
The syzkaller must have called connect() for an IPv6 address on
an IPv4 socket.
We have a proper validation in tcp_v[46]_connect(), but
security_socket_connect() is called in the earlier stage.
Let's copy the validation to netlbl_conn_setattr().
[0]:

CVE-2025-38100 (GCVE-0-2025-38100)

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/iopl: Cure TIF_IO_BITMAP inconsistencies
io_bitmap_exit() is invoked from exit_thread() when a task exists or
when a fork fails. In the latter case the exit_thread() cleans up
resources which were allocated during fork().
io_bitmap_exit() invokes task_update_io_bitmap(), which in turn ends up
in tss_update_io_bitmap(). tss_update_io_bitmap() operates on the
current task. If current has TIF_IO_BITMAP set, but no bitmap installed,
tss_update_io_bitmap() crashes with a NULL pointer dereference.
There are two issues, which lead to that problem:
1) io_bitmap_exit() should not invoke task_update_io_bitmap() when
the task, which is cleaned up, is not the current task. That's a
clear indicator for a cleanup after a failed fork().
2) A task should not have TIF_IO_BITMAP set and neither a bitmap
installed nor IOPL emulation level 3 activated.
This happens when a kernel thread is created in the context of
a user space thread, which has TIF_IO_BITMAP set as the thread
flags are copied and the IO bitmap pointer is cleared.
Other than in the failed fork() case this has no impact because
kernel threads including IO workers never return to user space and
therefore never invoke tss_update_io_bitmap().
Cure this by adding the missing cleanups and checks:
1) Prevent io_bitmap_exit() to invoke task_update_io_bitmap() if
the to be cleaned up task is not the current task.
2) Clear TIF_IO_BITMAP in copy_thread() unconditionally. For user
space forks it is set later, when the IO bitmap is inherited in
io_bitmap_share().
For paranoia sake, add a warning into tss_update_io_bitmap() to catch
the case, when that code is invoked with inconsistent state.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: p54: prevent buffer-overflow in p54_rx_eeprom_readback()
Robert Morris reported:
|If a malicious USB device pretends to be an Intersil p54 wifi
|interface and generates an eeprom_readback message with a large
|eeprom->v1.len, p54_rx_eeprom_readback() will copy data from the
|message beyond the end of priv->eeprom.
|
|static void p54_rx_eeprom_readback(struct p54_common *priv,
| struct sk_buff *skb)
|{
| struct p54_hdr *hdr = (struct p54_hdr *) skb->data;

|
| if (priv->fw_var >= 0x509) {
| memcpy(priv->eeprom, eeprom->v2.data,
| le16_to_cpu(eeprom->v2.len));
| } else {
| memcpy(priv->eeprom, eeprom->v1.data,
| le16_to_cpu(eeprom->v1.len));
| }
| [...]
The eeprom->v{1,2}.len is set by the driver in p54_download_eeprom().
The device is supposed to provide the same length back to the driver.
But yes, it's possible (like shown in the report) to alter the value
to something that causes a crash/panic due to overrun.
This patch addresses the issue by adding the size to the common device
context, so p54_rx_eeprom_readback no longer relies on possibly tampered
values... That said, it also checks if the "firmware" altered the value
and no longer copies them.
The one, small saving grace is: Before the driver tries to read the eeprom,
it needs to upload >a< firmware. the vendor firmware has a proprietary
license and as a reason, it is not present on most distributions by
default.

CVE-2025-37856 (GCVE-0-2025-37856)
Vulnerability from cvelistv5 – Published: 2025-05-09 06:42 – Updated: 2025-05-26 05:22

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: harden block_group::bg_list against list_del() races
As far as I can tell, these calls of list_del_init() on bg_list cannot
run concurrently with btrfs_mark_bg_unused() or btrfs_mark_bg_to_reclaim(),
as they are in transaction error paths and situations where the block
group is readonly.
However, if there is any chance at all of racing with mark_bg_unused(),
or a different future user of bg_list, better to be safe than sorry.
Otherwise we risk the following interleaving (bg_list refcount in parens)
T1 (some random op) T2 (btrfs_mark_bg_unused)
!list_empty(&bg->bg_list); (1)
list_del_init(&bg->bg_list); (1)
list_move_tail (1)
btrfs_put_block_group (0)
btrfs_delete_unused_bgs
bg = list_first_entry
list_del_init(&bg->bg_list);
btrfs_put_block_group(bg); (-1)
Ultimately, this results in a broken ref count that hits zero one deref
early and the real final deref underflows the refcount, resulting in a WARNING.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gve: add missing NULL check for gve_alloc_pending_packet() in TX DQO
gve_alloc_pending_packet() can return NULL, but gve_tx_add_skb_dqo()
did not check for this case before dereferencing the returned pointer.
Add a missing NULL check to prevent a potential NULL pointer
dereference when allocation fails.
This improves robustness in low-memory scenarios.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: tcpm: move tcpm_queue_vdm_unlocked to asynchronous work
A state check was previously added to tcpm_queue_vdm_unlocked to
prevent a deadlock where the DisplayPort Alt Mode driver would be
executing work and attempting to grab the tcpm_lock while the TCPM
was holding the lock and attempting to unregister the altmode, blocking
on the altmode driver's cancel_work_sync call.
Because the state check isn't protected, there is a small window
where the Alt Mode driver could determine that the TCPM is
in a ready state and attempt to grab the lock while the
TCPM grabs the lock and changes the TCPM state to one that
causes the deadlock. The callstack is provided below:

CVE-2025-38272 (GCVE-0-2025-38272)
Vulnerability from cvelistv5 – Published: 2025-07-10 07:41 – Updated: 2025-09-09 17:06
VLAI?
EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: b53: do not enable EEE on bcm63xx
BCM63xx internal switches do not support EEE, but provide multiple RGMII
ports where external PHYs may be connected. If one of these PHYs are EEE
capable, we may try to enable EEE for the MACs, which then hangs the
system on access of the (non-existent) EEE registers.
Fix this by checking if the switch actually supports EEE before
attempting to configure it.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbcon: Make sure modelist not set on unregistered console
It looks like attempting to write to the "store_modes" sysfs node will
run afoul of unregistered consoles:
UBSAN: array-index-out-of-bounds in drivers/video/fbdev/core/fbcon.c:122:28
index -1 is out of range for type 'fb_info *[32]'
...
fbcon_info_from_console+0x192/0x1a0 drivers/video/fbdev/core/fbcon.c:122
fbcon_new_modelist+0xbf/0x2d0 drivers/video/fbdev/core/fbcon.c:3048
fb_new_modelist+0x328/0x440 drivers/video/fbdev/core/fbmem.c:673
store_modes+0x1c9/0x3e0 drivers/video/fbdev/core/fbsysfs.c:113
dev_attr_store+0x55/0x80 drivers/base/core.c:2439
static struct fb_info *fbcon_registered_fb[FB_MAX];
...
static signed char con2fb_map[MAX_NR_CONSOLES];
...
static struct fb_info *fbcon_info_from_console(int console)
...
return fbcon_registered_fb[con2fb_map[console]];
If con2fb_map contains a -1 things go wrong here. Instead, return NULL,
as callers of fbcon_info_from_console() are trying to compare against
existing "info" pointers, so error handling should kick in correctly.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
VMCI: fix race between vmci_host_setup_notify and vmci_ctx_unset_notify
During our test, it is found that a warning can be trigger in try_grab_folio
as follow:

Digging into the source, context->notify_page may init by get_user_pages_fast
and can be seen in vmci_ctx_unset_notify which will try to put_page. However
get_user_pages_fast is not finished here and lead to following
try_grab_folio warning. The race condition is shown as follow:
cpu0 cpu1
vmci_host_do_set_notify
vmci_host_setup_notify
get_user_pages_fast(uva, 1, FOLL_WRITE, &context->notify_page);
lockless_pages_from_mm
gup_pgd_range
gup_huge_pmd // update &context->notify_page
vmci_host_do_set_notify
vmci_ctx_unset_notify
notify_page = context->notify_page;
if (notify_page)
put_page(notify_page); // page is freed
__gup_longterm_locked
__get_user_pages
follow_trans_huge_pmd
try_grab_folio // warn here
To slove this, use local variable page to make notify_page can be seen
after finish get_user_pages_fast.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: vlan: fix VLAN 0 refcount imbalance of toggling filtering during runtime
Assuming the "rx-vlan-filter" feature is enabled on a net device, the
8021q module will automatically add or remove VLAN 0 when the net device
is put administratively up or down, respectively. There are a couple of
problems with the above scheme.
The first problem is a memory leak that can happen if the "rx-vlan-filter"
feature is disabled while the device is running:
# ip link add bond1 up type bond mode 0
# ethtool -K bond1 rx-vlan-filter off
# ip link del dev bond1
When the device is put administratively down the "rx-vlan-filter"
feature is disabled, so the 8021q module will not remove VLAN 0 and the
memory will be leaked [1].
Another problem that can happen is that the kernel can automatically
delete VLAN 0 when the device is put administratively down despite not
adding it when the device was put administratively up since during that
time the "rx-vlan-filter" feature was disabled. null-ptr-unref or
bug_on[2] will be triggered by unregister_vlan_dev() for refcount
imbalance if toggling filtering during runtime:
$ ip link add bond0 type bond mode 0
$ ip link add link bond0 name vlan0 type vlan id 0 protocol 802.1q
$ ethtool -K bond0 rx-vlan-filter off
$ ifconfig bond0 up
$ ethtool -K bond0 rx-vlan-filter on
$ ifconfig bond0 down
$ ip link del vlan0
Root cause is as below:
step1: add vlan0 for real_dev, such as bond, team.
register_vlan_dev
vlan_vid_add(real_dev,htons(ETH_P_8021Q),0) //refcnt=1
step2: disable vlan filter feature and enable real_dev
step3: change filter from 0 to 1
vlan_device_event
vlan_filter_push_vids
ndo_vlan_rx_add_vid //No refcnt added to real_dev vlan0
step4: real_dev down
vlan_device_event
vlan_vid_del(dev, htons(ETH_P_8021Q), 0); //refcnt=0
vlan_info_rcu_free //free vlan0
step5: delete vlan0
unregister_vlan_dev
BUG_ON(!vlan_info); //vlan_info is null
Fix both problems by noting in the VLAN info whether VLAN 0 was
automatically added upon NETDEV_UP and based on that decide whether it
should be deleted upon NETDEV_DOWN, regardless of the state of the
"rx-vlan-filter" feature.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: vlan: fix VLAN 0 refcount imbalance of toggling filtering during runtime\n\nAssuming the \"rx-vlan-filter\" feature is enabled on a net device, the\n8021q module will automatically add or remove VLAN 0 when the net device\nis put administratively up or down, respectively. There are a couple of\nproblems with the above scheme.\n\nThe first problem is a memory leak that can happen if the \"rx-vlan-filter\"\nfeature is disabled while the device is running:\n\n # ip link add bond1 up type bond mode 0\n # ethtool -K bond1 rx-vlan-filter off\n # ip link del dev bond1\n\nWhen the device is put administratively down the \"rx-vlan-filter\"\nfeature is disabled, so the 8021q module will not remove VLAN 0 and the\nmemory will be leaked [1].\n\nAnother problem that can happen is that the kernel can automatically\ndelete VLAN 0 when the device is put administratively down despite not\nadding it when the device was put administratively up since during that\ntime the \"rx-vlan-filter\" feature was disabled. null-ptr-unref or\nbug_on[2] will be triggered by unregister_vlan_dev() for refcount\nimbalance if toggling filtering during runtime:\n\n$ ip link add bond0 type bond mode 0\n$ ip link add link bond0 name vlan0 type vlan id 0 protocol 802.1q\n$ ethtool -K bond0 rx-vlan-filter off\n$ ifconfig bond0 up\n$ ethtool -K bond0 rx-vlan-filter on\n$ ifconfig bond0 down\n$ ip link del vlan0\n\nRoot cause is as below:\nstep1: add vlan0 for real_dev, such as bond, team.\nregister_vlan_dev\n vlan_vid_add(real_dev,htons(ETH_P_8021Q),0) //refcnt=1\nstep2: disable vlan filter feature and enable real_dev\nstep3: change filter from 0 to 1\nvlan_device_event\n vlan_filter_push_vids\n ndo_vlan_rx_add_vid //No refcnt added to real_dev vlan0\nstep4: real_dev down\nvlan_device_event\n vlan_vid_del(dev, htons(ETH_P_8021Q), 0); //refcnt=0\n vlan_info_rcu_free //free vlan0\nstep5: delete vlan0\nunregister_vlan_dev\n BUG_ON(!vlan_info); //vlan_info is null\n\nFix both problems by noting in the VLAN info whether VLAN 0 was\nautomatically added upon NETDEV_UP and based on that decide whether it\nshould be deleted upon NETDEV_DOWN, regardless of the state of the\n\"rx-vlan-filter\" feature.\n\n[1]\nunreferenced object 0xffff8880068e3100 (size 256):\n comm \"ip\", pid 384, jiffies 4296130254\n hex dump (first 32 bytes):\n 00 20 30 0d 80 88 ff ff 00 00 00 00 00 00 00 00 . 0.............\n 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................\n backtrace (crc 81ce31fa):\n __kmalloc_cache_noprof+0x2b5/0x340\n vlan_vid_add+0x434/0x940\n vlan_device_event.cold+0x75/0xa8\n notifier_call_chain+0xca/0x150\n __dev_notify_flags+0xe3/0x250\n rtnl_configure_link+0x193/0x260\n rtnl_newlink_create+0x383/0x8e0\n __rtnl_newlink+0x22c/0xa40\n rtnl_newlink+0x627/0xb00\n rtnetlink_rcv_msg+0x6fb/0xb70\n netlink_rcv_skb+0x11f/0x350\n netlink_unicast+0x426/0x710\n netlink_sendmsg+0x75a/0xc20\n __sock_sendmsg+0xc1/0x150\n ____sys_sendmsg+0x5aa/0x7b0\n ___sys_sendmsg+0xfc/0x180\n\n[2]\nkernel BUG at net/8021q/vlan.c:99!\nOops: invalid opcode: 0000 [#1] SMP KASAN PTI\nCPU: 0 UID: 0 PID: 382 Comm: ip Not tainted 6.16.0-rc3 #61 PREEMPT(voluntary)\nHardware name: QEMU Standard PC (i440FX + PIIX, 1996),\nBIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014\nRIP: 0010:unregister_vlan_dev (net/8021q/vlan.c:99 (discriminator 1))\nRSP: 0018:ffff88810badf310 EFLAGS: 00010246\nRAX: 0000000000000000 RBX: ffff88810da84000 RCX: ffffffffb47ceb9a\nRDX: dffffc0000000000 RSI: 0000000000000008 RDI: ffff88810e8b43c8\nRBP: 0000000000000000 R08: 0000000000000000 R09: fffffbfff6cefe80\nR10: ffffffffb677f407 R11: ffff88810badf3c0 R12: ffff88810e8b4000\nR13: 0000000000000000 R14: ffff88810642a5c0 R15: 000000000000017e\nFS: 00007f1ff68c20c0(0000) GS:ffff888163a24000(0000) knlGS:0000000000000000\nCS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 00007f1ff5dad240 CR3: 0000000107e56000 CR4: 00000000000006f0\nCall Trace:\n \u003cTASK\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
espintcp: remove encap socket caching to avoid reference leak
The current scheme for caching the encap socket can lead to reference
leaks when we try to delete the netns.
The reference chain is: xfrm_state -> enacp_sk -> netns
Since the encap socket is a userspace socket, it holds a reference on
the netns. If we delete the espintcp state (through flush or
individual delete) before removing the netns, the reference on the
socket is dropped and the netns is correctly deleted. Otherwise, the
netns may not be reachable anymore (if all processes within the ns
have terminated), so we cannot delete the xfrm state to drop its
reference on the socket.
This patch results in a small (~2% in my tests) performance
regression.
A GC-type mechanism could be added for the socket cache, to clear
references if the state hasn't been used "recently", but it's a lot
more complex than just not caching the socket.
Severity ?
No CVSS data available.

net/tipc: fix slab-use-after-free Read in tipc_aead_encrypt_done
Syzbot reported a slab-use-after-free with the following call trace:

After freed the tipc_crypto tx by delete namespace, tipc_aead_encrypt_done
may still visit it in cryptd_queue_worker workqueue.
I reproduce this issue by:
ip netns add ns1
ip link add veth1 type veth peer name veth2
ip link set veth1 netns ns1
ip netns exec ns1 tipc bearer enable media eth dev veth1
ip netns exec ns1 tipc node set key this_is_a_master_key master
ip netns exec ns1 tipc bearer disable media eth dev veth1
ip netns del ns1
The key of reproduction is that, simd_aead_encrypt is interrupted, leading
to crypto_simd_usable() return false. Thus, the cryptd_queue_worker is
triggered, and the tipc_crypto tx will be visited.
tipc_disc_timeout
tipc_bearer_xmit_skb
tipc_crypto_xmit
tipc_aead_encrypt
crypto_aead_encrypt
// encrypt()
simd_aead_encrypt
// crypto_simd_usable() is false
child = &ctx->cryptd_tfm->base;
simd_aead_encrypt
crypto_aead_encrypt
// encrypt()
cryptd_aead_encrypt_enqueue
cryptd_aead_enqueue
cryptd_enqueue_request
// trigger cryptd_queue_worker
queue_work_on(smp_processor_id(), cryptd_wq, &cpu_queue->work)
Fix this by holding net reference count before encrypt.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: u_serial: Fix race condition in TTY wakeup
A race condition occurs when gs_start_io() calls either gs_start_rx() or
gs_start_tx(), as those functions briefly drop the port_lock for
usb_ep_queue(). This allows gs_close() and gserial_disconnect() to clear
port.tty and port_usb, respectively.
Use the null-safe TTY Port helper function to wake up TTY.
Example
CPU1: CPU2:
gserial_connect() // lock
gs_close() // await lock
gs_start_rx() // unlock
usb_ep_queue()
gs_close() // lock, reset port.tty and unlock
gs_start_rx() // lock
tty_wakeup() // NPE
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vhost-scsi: protect vq->log_used with vq->mutex
The vhost-scsi completion path may access vq->log_base when vq->log_used is
already set to false.
vhost-thread QEMU-thread
vhost_scsi_complete_cmd_work()
-> vhost_add_used()
-> vhost_add_used_n()
if (unlikely(vq->log_used))
QEMU disables vq->log_used
via VHOST_SET_VRING_ADDR.
mutex_lock(&vq->mutex);
vq->log_used = false now!
mutex_unlock(&vq->mutex);
QEMU gfree(vq->log_base)
log_used()
-> log_write(vq->log_base)
Assuming the VMM is QEMU. The vq->log_base is from QEMU userpace and can be
reclaimed via gfree(). As a result, this causes invalid memory writes to
QEMU userspace.
The control queue path has the same issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/mm/pat: Fix VM_PAT handling when fork() fails in copy_page_range()
If track_pfn_copy() fails, we already added the dst VMA to the maple
tree. As fork() fails, we'll cleanup the maple tree, and stumble over
the dst VMA for which we neither performed any reservation nor copied
any page tables.
Consequently untrack_pfn() will see VM_PAT and try obtaining the
PAT information from the page table -- which fails because the page
table was not copied.
The easiest fix would be to simply clear the VM_PAT flag of the dst VMA
if track_pfn_copy() fails. However, the whole thing is about "simply"
clearing the VM_PAT flag is shaky as well: if we passed track_pfn_copy()
and performed a reservation, but copying the page tables fails, we'll
simply clear the VM_PAT flag, not properly undoing the reservation ...
which is also wrong.
So let's fix it properly: set the VM_PAT flag only if the reservation
succeeded (leaving it clear initially), and undo the reservation if
anything goes wrong while copying the page tables: clearing the VM_PAT
flag after undoing the reservation.
Note that any copied page table entries will get zapped when the VMA will
get removed later, after copy_page_range() succeeded; as VM_PAT is not set
then, we won't try cleaning VM_PAT up once more and untrack_pfn() will be
happy. Note that leaving these page tables in place without a reservation
is not a problem, as we are aborting fork(); this process will never run.
A reproducer can trigger this usually at the first try:

Likely this case was missed in:

... and instead of undoing the reservation we simply cleared the VM_PAT flag.
Keep the documentation of these functions in include/linux/pgtable.h,
one place is more than sufficient -- we should clean that up for the other
functions like track_pfn_remap/untrack_pfn separately.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: gpio-keys - fix a sleep while atomic with PREEMPT_RT
When enabling PREEMPT_RT, the gpio_keys_irq_timer() callback runs in
hard irq context, but the input_event() takes a spin_lock, which isn't
allowed there as it is converted to a rt_spin_lock().
[ 4054.289999] BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48
[ 4054.290028] in_atomic(): 1, irqs_disabled(): 1, non_block: 0, pid: 0, name: swapper/0

[ 4054.290307] generic_handle_domain_irq+0x1c/0x28
[ 4054.290316] gic_handle_irq+0x44/0xcc
Considering the gpio_keys_irq_isr() can run in any context, e.g. it can
be threaded, it seems there's no point in requesting the timer isr to
run in hard irq context.
Relax the hrtimer not to use the hard context.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix iteration of extrefs during log replay
At __inode_add_ref() when processing extrefs, if we jump into the next
label we have an undefined value of victim_name.len, since we haven't
initialized it before we did the goto. This results in an invalid memory
access in the next iteration of the loop since victim_name.len was not
initialized to the length of the name of the current extref.
Fix this by initializing victim_name.len with the current extref's name
length.

CVE-2025-38460 (GCVE-0-2025-38460)

Summary
In the Linux kernel, the following vulnerability has been resolved:
atm: clip: Fix potential null-ptr-deref in to_atmarpd().
atmarpd is protected by RTNL since commit f3a0592b37b8 ("[ATM]: clip
causes unregister hang").
However, it is not enough because to_atmarpd() is called without RTNL,
especially clip_neigh_solicit() / neigh_ops->solicit() is unsleepable.
Also, there is no RTNL dependency around atmarpd.
Let's use a private mutex and RCU to protect access to atmarpd in
to_atmarpd().
Severity ?

root cause is:
page_pool_recycle_in_ring
ptr_ring_produce
spin_lock(&r->producer_lock);
WRITE_ONCE(r->queue[r->producer++], ptr)
//recycle last page to pool
page_pool_release
page_pool_scrub
page_pool_empty_ring
ptr_ring_consume
page_pool_return_page //release all page
__page_pool_destroy
free_percpu(pool->recycle_stats);
free(pool) //free
spin_unlock(&r->producer_lock); //pool->ring uaf read
recycle_stat_inc(pool, ring);
page_pool can be free while page pool recycle the last page in ring.
Add producer-lock barrier to page_pool_release to prevent the page
pool from being free before all pages have been recycled.
recycle_stat_inc() is empty when CONFIG_PAGE_POOL_STATS is not
enabled, which will trigger Wempty-body build warning. Add definition
for pool stat macro to fix warning.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: idxd: Check availability of workqueue allocated by idxd wq driver before using
Running IDXD workloads in a container with the /dev directory mounted can
trigger a call trace or even a kernel panic when the parent process of the
container is terminated.
This issue occurs because, under certain configurations, Docker does not
properly propagate the mount replica back to the original mount point.
In this case, when the user driver detaches, the WQ is destroyed but it
still calls destroy_workqueue() attempting to completes all pending work.
It's necessary to check wq->wq and skip the drain if it no longer exists.
Severity ?
No CVSS data available.

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/exynos: exynos7_drm_decon: add vblank check in IRQ handling
If there's support for another console device (such as a TTY serial),
the kernel occasionally panics during boot. The panic message and a
relevant snippet of the call stack is as follows:
Unable to handle kernel NULL pointer dereference at virtual address 000000000000000
Call trace:
drm_crtc_handle_vblank+0x10/0x30 (P)
decon_irq_handler+0x88/0xb4
[...]
Otherwise, the panics don't happen. This indicates that it's some sort
of race condition.
Add a check to validate if the drm device can handle vblanks before
calling drm_crtc_handle_vblank() to avoid this.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: wwan: t7xx: Fix napi rx poll issue
When driver handles the napi rx polling requests, the netdev might
have been released by the dellink logic triggered by the disconnect
operation on user plane. However, in the logic of processing skb in
polling, an invalid netdev is still being used, which causes a panic.

Summary
In the Linux kernel, the following vulnerability has been resolved:
IB/mlx5: Fix potential deadlock in MR deregistration
The issue arises when kzalloc() is invoked while holding umem_mutex or
any other lock acquired under umem_mutex. This is problematic because
kzalloc() can trigger fs_reclaim_aqcuire(), which may, in turn, invoke
mmu_notifier_invalidate_range_start(). This function can lead to
mlx5_ib_invalidate_range(), which attempts to acquire umem_mutex again,
resulting in a deadlock.
The problematic flow:
CPU0 | CPU1
---------------------------------------|------------------------------------------------
mlx5_ib_dereg_mr() |
→ revoke_mr() |
→ mutex_lock(&umem_odp->umem_mutex) |
| mlx5_mkey_cache_init()
| → mutex_lock(&dev->cache.rb_lock)
| → mlx5r_cache_create_ent_locked()
| → kzalloc(GFP_KERNEL)
| → fs_reclaim()
| → mmu_notifier_invalidate_range_start()
| → mlx5_ib_invalidate_range()
| → mutex_lock(&umem_odp->umem_mutex)
→ cache_ent_find_and_store() |
→ mutex_lock(&dev->cache.rb_lock) |
Additionally, when kzalloc() is called from within
cache_ent_find_and_store(), we encounter the same deadlock due to
re-acquisition of umem_mutex.
Solve by releasing umem_mutex in dereg_mr() after umr_revoke_mr()
and before acquiring rb_lock. This ensures that we don't hold
umem_mutex while performing memory allocations that could trigger
the reclaim path.
This change prevents the deadlock by ensuring proper lock ordering and
avoiding holding locks during memory allocation operations that could
trigger the reclaim path.
The following lockdep warning demonstrates the deadlock:
python3/20557 is trying to acquire lock:

Summary
In the Linux kernel, the following vulnerability has been resolved:
e1000: Move cancel_work_sync to avoid deadlock
Previously, e1000_down called cancel_work_sync for the e1000 reset task
(via e1000_down_and_stop), which takes RTNL.
As reported by users and syzbot, a deadlock is possible in the following
scenario:
CPU 0:
- RTNL is held
- e1000_close
- e1000_down
- cancel_work_sync (cancel / wait for e1000_reset_task())
CPU 1:
- process_one_work
- e1000_reset_task
- take RTNL
To remedy this, avoid calling cancel_work_sync from e1000_down
(e1000_reset_task does nothing if the device is down anyway). Instead,
call cancel_work_sync for e1000_reset_task when the device is being
removed.
Severity ?

Summary
In the Linux kernel, the following vulnerability has been resolved:
comedi: Fix use of uninitialized data in insn_rw_emulate_bits()
For Comedi `INSN_READ` and `INSN_WRITE` instructions on "digital"
subdevices (subdevice types `COMEDI_SUBD_DI`, `COMEDI_SUBD_DO`, and
`COMEDI_SUBD_DIO`), it is common for the subdevice driver not to have
`insn_read` and `insn_write` handler functions, but to have an
`insn_bits` handler function for handling Comedi `INSN_BITS`
instructions. In that case, the subdevice's `insn_read` and/or
`insn_write` function handler pointers are set to point to the
`insn_rw_emulate_bits()` function by `__comedi_device_postconfig()`.
For `INSN_WRITE`, `insn_rw_emulate_bits()` currently assumes that the
supplied `data[0]` value is a valid copy from user memory. It will at
least exist because `do_insnlist_ioctl()` and `do_insn_ioctl()` in
"comedi_fops.c" ensure at lease `MIN_SAMPLES` (16) elements are
allocated. However, if `insn->n` is 0 (which is allowable for
`INSN_READ` and `INSN_WRITE` instructions, then `data[0]` may contain
uninitialized data, and certainly contains invalid data, possibly from a
different instruction in the array of instructions handled by
`do_insnlist_ioctl()`. This will result in an incorrect value being
written to the digital output channel (or to the digital input/output
channel if configured as an output), and may be reflected in the
internal saved state of the channel.
Fix it by returning 0 early if `insn->n` is 0, before reaching the code
that accesses `data[0]`. Previously, the function always returned 1 on
success, but it is supposed to be the number of data samples actually
read or written up to `insn->n`, which is 0 in this case.

CVE-2025-38429 (GCVE-0-2025-38429)
Vulnerability from cvelistv5 – Published: 2025-07-25 14:16 – Updated: 2025-07-28 04:21

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
bus: mhi: ep: Update read pointer only after buffer is written
Inside mhi_ep_ring_add_element, the read pointer (rd_offset) is updated
before the buffer is written, potentially causing race conditions where
the host sees an updated read pointer before the buffer is actually
written. Updating rd_offset prematurely can lead to the host accessing
an uninitialized or incomplete element, resulting in data corruption.
Invoke the buffer write before updating rd_offset to ensure the element
is fully written before signaling its availability.
Severity ?
No CVSS data available.

CVE-2025-38497 (GCVE-0-2025-38497)

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: configfs: Fix OOB read on empty string write
When writing an empty string to either 'qw_sign' or 'landingPage'
sysfs attributes, the store functions attempt to access page[l - 1]
before validating that the length 'l' is greater than zero.
This patch fixes the vulnerability by adding a check at the beginning
of os_desc_qw_sign_store() and webusb_landingPage_store() to handle
the zero-length input case gracefully by returning immediately.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mdiobus: Fix potential out-of-bounds read/write access
When using publicly available tools like 'mdio-tools' to read/write data
from/to network interface and its PHY via mdiobus, there is no verification of
parameters passed to the ioctl and it accepts any mdio address.
Currently there is support for 32 addresses in kernel via PHY_MAX_ADDR define,
but it is possible to pass higher value than that via ioctl.
While read/write operation should generally fail in this case,
mdiobus provides stats array, where wrong address may allow out-of-bounds
read/write.
Fix that by adding address verification before read/write operation.
While this excludes this access from any statistics, it improves security of
read/write operation.
Severity ?
No CVSS data available.

5 bytes:
void rtw_fw_bt_wifi_control(struct rtw_dev *rtwdev, u8 op_code, u8 *data)
{
...
SET_BT_WIFI_CONTROL_DATA1(h2c_pkt, *data);

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm-bufio: fix sched in atomic context
If "try_verify_in_tasklet" is set for dm-verity, DM_BUFIO_CLIENT_NO_SLEEP
is enabled for dm-bufio. However, when bufio tries to evict buffers, there
is a chance to trigger scheduling in spin_lock_bh, the following warning
is hit:

Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: always refresh the queue when reading sock
After recent changes in net-next TCP compacts skbs much more
aggressively. This unearthed a bug in TLS where we may try
to operate on an old skb when checking if all skbs in the
queue have matching decrypt state and geometry.
BUG: KASAN: slab-use-after-free in tls_strp_check_rcv+0x898/0x9a0 [tls]

CPU: 2 UID: 0 PID: 13529 Comm: tls Not tainted 6.16.0-rc5-virtme

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix out-of-bounds read in snd_usb_get_audioformat_uac3()
In snd_usb_get_audioformat_uac3(), the length value returned from
snd_usb_ctl_msg() is used directly for memory allocation without
validation. This length is controlled by the USB device.
The allocated buffer is cast to a uac3_cluster_header_descriptor
and its fields are accessed without verifying that the buffer
is large enough. If the device returns a smaller than expected
length, this leads to an out-of-bounds read.
Add a length check to ensure the buffer is large enough for
uac3_cluster_header_descriptor.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: core: do not bypass hid_hw_raw_request
hid_hw_raw_request() is actually useful to ensure the provided buffer
and length are valid. Directly calling in the low level transport driver
function bypassed those checks and allowed invalid paramto be used.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: phy: clear phydev->devlink when the link is deleted
There is a potential crash issue when disabling and re-enabling the
network port. When disabling the network port, phy_detach() calls
device_link_del() to remove the device link, but it does not clear
phydev->devlink, so phydev->devlink is not a NULL pointer. Then the
network port is re-enabled, but if phy_attach_direct() fails before
calling device_link_add(), the code jumps to the "error" label and
calls phy_detach(). Since phydev->devlink retains the old value from
the previous attach/detach cycle, device_link_del() uses the old value,
which accesses a NULL pointer and causes a crash. The simplified crash
log is as follows.
[ 24.702421] Call trace:
[ 24.704856] device_link_put_kref+0x20/0x120
[ 24.709124] device_link_del+0x30/0x48
[ 24.712864] phy_detach+0x24/0x168
[ 24.716261] phy_attach_direct+0x168/0x3a4
[ 24.720352] phylink_fwnode_phy_connect+0xc8/0x14c
[ 24.725140] phylink_of_phy_connect+0x1c/0x34
Therefore, phydev->devlink needs to be cleared when the device link is
deleted.

127.
Added a bound check for that error and return -EIO if the check fails.
Also make jfs_readdir return with error if add_missing_indices returns
with an error.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: fix udp gso skb_segment after pull from frag_list
Commit a1e40ac5b5e9 ("net: gso: fix udp gso fraglist segmentation after
pull from frag_list") detected invalid geometry in frag_list skbs and
redirects them from skb_segment_list to more robust skb_segment. But some
packets with modified geometry can also hit bugs in that code. We don't
know how many such cases exist. Addressing each one by one also requires
touching the complex skb_segment code, which risks introducing bugs for
other types of skbs. Instead, linearize all these packets that fail the
basic invariants on gso fraglist skbs. That is more robust.
If only part of the fraglist payload is pulled into head_skb, it will
always cause exception when splitting skbs by skb_segment. For detailed
call stack information, see below.
Valid SKB_GSO_FRAGLIST skbs
- consist of two or more segments
- the head_skb holds the protocol headers plus first gso_size
- one or more frag_list skbs hold exactly one segment
- all but the last must be gso_size
Optional datapath hooks such as NAT and BPF (bpf_skb_pull_data) can
modify fraglist skbs, breaking these invariants.
In extreme cases they pull one part of data into skb linear. For UDP,
this causes three payloads with lengths of (11,11,10) bytes were
pulled tail to become (12,10,10) bytes.
The skbs no longer meets the above SKB_GSO_FRAGLIST conditions because
payload was pulled into head_skb, it needs to be linearized before pass
to regular skb_segment.

CVE-2025-38215 (GCVE-0-2025-38215)

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: Fix do_register_framebuffer to prevent null-ptr-deref in fb_videomode_to_var
If fb_add_videomode() in do_register_framebuffer() fails to allocate
memory for fb_videomode, it will later lead to a null-ptr dereference in
fb_videomode_to_var(), as the fb_info is registered while not having the
mode in modelist that is expected to be there, i.e. the one that is
described in fb_info->var.
================================================================
general protection fault, probably for non-canonical address 0xdffffc0000000001: 0000 [#1] PREEMPT SMP KASAN NOPTI

================================================================
Even though fbcon_init() checks beforehand if fb_match_mode() in
var_to_display() fails, it can not prevent the panic because fbcon_init()
does not return error code. Considering this and the comment in the code
about fb_match_mode() returning NULL - "This should not happen" - it is
better to prevent registering the fb_info if its mode was not set
successfully. Also move fb_add_videomode() closer to the beginning of
do_register_framebuffer() to avoid having to do the cleanup on fail.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: core: fbcvt: avoid division by 0 in fb_cvt_hperiod()
In fb_find_mode_cvt(), iff mode->refresh somehow happens to be 0x80000000,
cvt.f_refresh will become 0 when multiplying it by 2 due to overflow. It's
then passed to fb_cvt_hperiod(), where it's used as a divider -- division
by 0 will result in kernel oops. Add a sanity check for cvt.f_refresh to
avoid such overflow...
Found by Linux Verification Center (linuxtesting.org) with the Svace static
analysis tool.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPICA: fix acpi operand cache leak in dswstate.c
ACPICA commit 987a3b5cf7175916e2a4b6ea5b8e70f830dfe732
I found an ACPI cache leak in ACPI early termination and boot continuing case.
When early termination occurs due to malicious ACPI table, Linux kernel
terminates ACPI function and continues to boot process. While kernel terminates
ACPI function, kmem_cache_destroy() reports Acpi-Operand cache leak.
Boot log of ACPI operand cache leak is as follows:

I analyzed this memory leak in detail and found acpi_ds_obj_stack_pop_and_
delete() function miscalculated the top of the stack. acpi_ds_obj_stack_push()
function uses walk_state->operand_index for start position of the top, but
acpi_ds_obj_stack_pop_and_delete() function considers index 0 for it.
Therefore, this causes acpi operand memory leak.
This cache leak causes a security threat because an old kernel (<= 4.9) shows
memory locations of kernel functions in stack dump. Some malicious users
could use this information to neutralize kernel ASLR.
I made a patch to fix ACPI operand cache leak.

While kernel terminates\nACPI function, kmem_cache_destroy() reports Acpi-Operand cache leak.\n\nBoot log of ACPI operand cache leak is as follows:\n\u003e[ 0.585957] ACPI: Added _OSI(Module Device)\n\u003e[ 0.587218] ACPI: Added _OSI(Processor Device)\n\u003e[ 0.588530] ACPI: Added _OSI(3.0 _SCP Extensions)\n\u003e[ 0.589790] ACPI: Added _OSI(Processor Aggregator Device)\n\u003e[ 0.591534] ACPI Error: Illegal I/O port address/length above 64K: C806E00000004002/0x2 (20170303/hwvalid-155)\n\u003e[ 0.594351] ACPI Exception: AE_LIMIT, Unable to initialize fixed events (20170303/evevent-88)\n\u003e[ 0.597858] ACPI: Unable to start the ACPI Interpreter\n\u003e[ 0.599162] ACPI Error: Could not remove SCI handler (20170303/evmisc-281)\n\u003e[ 0.601836] kmem_cache_destroy Acpi-Operand: Slab cache still has objects\n\u003e[ 0.603556] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.12.0-rc5 #26\n\u003e[ 0.605159] Hardware name: innotek gmb_h virtual_box/virtual_box, BIOS virtual_box 12/01/2006\n\u003e[ 0.609177] Call Trace:\n\u003e[ 0.610063] ? dump_stack+0x5c/0x81\n\u003e[ 0.611118] ? kmem_cache_destroy+0x1aa/0x1c0\n\u003e[ 0.612632] ? acpi_sleep_proc_init+0x27/0x27\n\u003e[ 0.613906] ? acpi_os_delete_cache+0xa/0x10\n\u003e[ 0.617986] ? acpi_ut_delete_caches+0x3f/0x7b\n\u003e[ 0.619293] ? acpi_terminate+0xa/0x14\n\u003e[ 0.620394] ? acpi_init+0x2af/0x34f\n\u003e[ 0.621616] ? __class_create+0x4c/0x80\n\u003e[ 0.623412] ? video_setup+0x7f/0x7f\n\u003e[ 0.624585] ? acpi_sleep_proc_init+0x27/0x27\n\u003e[ 0.625861] ? do_one_initcall+0x4e/0x1a0\n\u003e[ 0.627513] ? kernel_init_freeable+0x19e/0x21f\n\u003e[ 0.628972] ? rest_init+0x80/0x80\n\u003e[ 0.630043] ? kernel_init+0xa/0x100\n\u003e[ 0.631084] ? ret_from_fork+0x25/0x30\n\u003e[ 0.633343] vgaarb: loaded\n\u003e[ 0.635036] EDAC MC: Ver: 3.0.0\n\u003e[ 0.638601] PCI: Probing PCI hardware\n\u003e[ 0.639833] PCI host bridge to bus 0000:00\n\u003e[ 0.641031] pci_bus 0000:00: root bus resource [io 0x0000-0xffff]\n\u003e ... Continue to boot and log is omitted ...\n\nI analyzed this memory leak in detail and found acpi_ds_obj_stack_pop_and_\ndelete() function miscalculated the top of the stack. acpi_ds_obj_stack_push()\nfunction uses walk_state-\u003eoperand_index for start position of the top, but\nacpi_ds_obj_stack_pop_and_delete() function considers index 0 for it.\nTherefore, this causes acpi operand memory leak.\n\nThis cache leak causes a security threat because an old kernel (\u003c= 4.9) shows\nmemory locations of kernel functions in stack dump. Some malicious users\ncould use this information to neutralize kernel ASLR.\n\nI made a patch to fix ACPI operand cache leak."

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k_htc: Abort software beacon handling if disabled
A malicious USB device can send a WMI_SWBA_EVENTID event from an
ath9k_htc-managed device before beaconing has been enabled. This causes
a device-by-zero error in the driver, leading to either a crash or an
out of bounds read.
Prevent this by aborting the handling in ath9k_htc_swba() if beacons are
not enabled.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: renesas_usbhs: Reorder clock handling and power management in probe
Reorder the initialization sequence in `usbhs_probe()` to enable runtime
PM before accessing registers, preventing potential crashes due to
uninitialized clocks.
Currently, in the probe path, registers are accessed before enabling the
clocks, leading to a synchronous external abort on the RZ/V2H SoC.
The problematic call flow is as follows:
usbhs_probe()
usbhs_sys_clock_ctrl()
usbhs_bset()
usbhs_write()
iowrite16() <-- Register access before enabling clocks
Since `iowrite16()` is performed without ensuring the required clocks are
enabled, this can lead to access errors. To fix this, enable PM runtime
early in the probe function and ensure clocks are acquired before register
access, preventing crashes like the following on RZ/V2H:

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: Prevent sending WMI commands to firmware during firmware crash
Currently, we encounter the following kernel call trace when a firmware
crash occurs. This happens because the host sends WMI commands to the
firmware while it is in recovery, causing the commands to fail and
resulting in the kernel call trace.
Set the ATH12K_FLAG_CRASH_FLUSH and ATH12K_FLAG_RECOVERY flags when the
host driver receives the firmware crash notification from MHI. This
prevents sending WMI commands to the firmware during recovery.
Call Trace:

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: sun8i-ce-cipher - fix error handling in sun8i_ce_cipher_prepare()
Fix two DMA cleanup issues on the error path in sun8i_ce_cipher_prepare():
1] If dma_map_sg() fails for areq->dst, the device driver would try to free
DMA memory it has not allocated in the first place. To fix this, on the
"theend_sgs" error path, call dma unmap only if the corresponding dma
map was successful.
2] If the dma_map_single() call for the IV fails, the device driver would
try to free an invalid DMA memory address on the "theend_iv" path:

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/pp: Fix potential NULL pointer dereference in atomctrl_initialize_mc_reg_table
The function atomctrl_initialize_mc_reg_table() and
atomctrl_initialize_mc_reg_table_v2_2() does not check the return
value of smu_atom_get_data_table(). If smu_atom_get_data_table()
fails to retrieve vram_info, it returns NULL which is later
dereferenced.
Severity ?

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm: Fix a fence leak in submit error path
In error paths, we could unref the submit without calling
drm_sched_entity_push_job(), so msm_job_free() will never get
called. Since drm_sched_job_cleanup() will NULL out the
s_fence, we can use that to detect this case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipc: fix to protect IPCS lookups using RCU
syzbot reported that it discovered a use-after-free vulnerability, [0]
[0]: https://lore.kernel.org/all/67af13f8.050a0220.21dd3.0038.GAE@google.com/
idr_for_each() is protected by rwsem, but this is not enough. If it is
not protected by RCU read-critical region, when idr_for_each() calls
radix_tree_node_free() through call_rcu() to free the radix_tree_node
structure, the node will be freed immediately, and when reading the next
node in radix_tree_for_each_slot(), the already freed memory may be read.
Therefore, we need to add code to make sure that idr_for_each() is
protected within the RCU read-critical region when we call it in
shm_destroy_orphaned().

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Fix null-ptr-deref in l2cap_sock_resume_cb()
syzbot reported null-ptr-deref in l2cap_sock_resume_cb(). [0]
l2cap_sock_resume_cb() has a similar problem that was fixed by commit
1bff51ea59a9 ("Bluetooth: fix use-after-free error in lock_sock_nested()").
Since both l2cap_sock_kill() and l2cap_sock_resume_cb() are executed
under l2cap_sock_resume_cb(), we can avoid the issue simply by checking
if chan->data is NULL.
Let's not access to the killed socket in l2cap_sock_resume_cb().

Summary
In the Linux kernel, the following vulnerability has been resolved:
smc: Fix various oops due to inet_sock type confusion.
syzbot reported weird splats [0][1] in cipso_v4_sock_setattr() while
freeing inet_sk(sk)->inet_opt.
The address was freed multiple times even though it was read-only memory.
cipso_v4_sock_setattr() did nothing wrong, and the root cause was type
confusion.
The cited commit made it possible to create smc_sock as an INET socket.
The issue is that struct smc_sock does not have struct inet_sock as the
first member but hijacks AF_INET and AF_INET6 sk_family, which confuses
various places.
In this case, inet_sock.inet_opt was actually smc_sock.clcsk_data_ready(),
which is an address of a function in the text segment.
$ pahole -C inet_sock vmlinux
struct inet_sock {
...
struct ip_options_rcu * inet_opt; /* 784 8 */
$ pahole -C smc_sock vmlinux
struct smc_sock {
...
void (*clcsk_data_ready)(struct sock *); /* 784 8 */
The same issue for another field was reported before. [2][3]
At that time, an ugly hack was suggested [4], but it makes both INET
and SMC code error-prone and hard to change.
Also, yet another variant was fixed by a hacky commit 98d4435efcbf3
("net/smc: prevent NULL pointer dereference in txopt_get").
Instead of papering over the root cause by such hacks, we should not
allow non-INET socket to reuse the INET infra.
Let's add inet_sock as the first member of smc_sock.

[2][3]\n\nAt that time, an ugly hack was suggested [4], but it makes both INET\nand SMC code error-prone and hard to change.\n\nAlso, yet another variant was fixed by a hacky commit 98d4435efcbf3\n(\"net/smc: prevent NULL pointer dereference in txopt_get\").\n\nInstead of papering over the root cause by such hacks, we should not\nallow non-INET socket to reuse the INET infra.\n\nLet\u0027s add inet_sock as the first member of smc_sock.\n\n[0]:\nkvfree_call_rcu(): Double-freed call. rcu_head 000000006921da73\nWARNING: CPU: 0 PID: 6718 at mm/slab_common.c:1956 kvfree_call_rcu+0x94/0x3f0 mm/slab_common.c:1955\nModules linked in:\nCPU: 0 UID: 0 PID: 6718 Comm: syz.0.17 Tainted: G W 6.16.0-rc4-syzkaller-g7482bb149b9f #0 PREEMPT\nTainted: [W]=WARN\nHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 05/07/2025\npstate: 60400005 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--)\npc : kvfree_call_rcu+0x94/0x3f0 mm/slab_common.c:1955\nlr : kvfree_call_rcu+0x94/0x3f0 mm/slab_common.c:1955\nsp : ffff8000a03a7730\nx29: ffff8000a03a7730 x28: 00000000fffffff5 x27: 1fffe000184823d3\nx26: dfff800000000000 x25: ffff0000c2411e9e x24: ffff0000dd88da00\nx23: ffff8000891ac9a0 x22: 00000000ffffffea x21: ffff8000891ac9a0\nx20: ffff8000891ac9a0 x19: ffff80008afc2480 x18: 00000000ffffffff\nx17: 0000000000000000 x16: ffff80008ae642c8 x15: ffff700011ede14c\nx14: 1ffff00011ede14c x13: 0000000000000004 x12: ffffffffffffffff\nx11: ffff700011ede14c x10: 0000000000ff0100 x9 : 5fa3c1ffaf0ff000\nx8 : 5fa3c1ffaf0ff000 x7 : 0000000000000001 x6 : 0000000000000001\nx5 : ffff8000a03a7078 x4 : ffff80008f766c20 x3 : ffff80008054d360\nx2 : 0000000000000000 x1 : 0000000000000201 x0 : 0000000000000000\nCall trace:\n kvfree_call_rcu+0x94/0x3f0 mm/slab_common.c:1955 (P)\n cipso_v4_sock_setattr+0x2f0/0x3f4 net/ipv4/cipso_ipv4.c:1914\n netlbl_sock_setattr+0x240/0x334 net/netlabel/netlabel_kapi.c:1000\n smack_netlbl_add+0xa8/0x158 security/smack/smack_lsm.c:2581\n smack_inode_setsecurity+0x378/0x430 security/smack/smack_lsm.c:2912\n security_inode_setsecurity+0x118/0x3c0 security/security.c:2706\n __vfs_setxattr_noperm+0x174/0x5c4 fs/xattr.c:251\n __vfs_setxattr_locked+0x1ec/0x218 fs/xattr.c:295\n vfs_setxattr+0x158/0x2ac fs/xattr.c:321\n do_setxattr fs/xattr.c:636 [inline]\n file_setxattr+0x1b8/0x294 fs/xattr.c:646\n path_setxattrat+0x2ac/0x320 fs/xattr.c:711\n __do_sys_fsetxattr fs/xattr.c:761 [inline]\n __se_sys_fsetxattr fs/xattr.c:758 [inline]\n __arm64_sys_fsetxattr+0xc0/0xdc fs/xattr.c:758\n __invoke_syscall arch/arm64/kernel/syscall.c:35 [inline]\n invoke_syscall+0x98/0x2b8 arch/arm64/kernel/syscall.c:49\n el0_svc_common+0x130/0x23c arch/arm64/kernel/syscall.c:132\n do_el0_svc+0x48/0x58 arch/arm64/kernel/syscall.c:151\n el0_svc+0x58/0x180 arch/arm64/kernel/entry-common.c:879\n el0t_64_sync_handler+0x84/0x12c arch/arm64/kernel/entry-common.c:898\n el0t_64_sync+0x198/0x19c arch/arm64/kernel/entry.S:600\n\n[\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: atm: add lec_mutex
syzbot found its way in net/atm/lec.c, and found an error path
in lecd_attach() could leave a dangling pointer in dev_lec[].
Add a mutex to protect dev_lecp[] uses from lecd_attach(),
lec_vcc_attach() and lec_mcast_attach().
Following patch will use this mutex for /proc/net/atm/lec.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: displayport: Fix potential deadlock
The deadlock can occur due to a recursive lock acquisition of
`cros_typec_altmode_data::mutex`.
The call chain is as follows:
1. cros_typec_altmode_work() acquires the mutex
2. typec_altmode_vdm() -> dp_altmode_vdm() ->
3. typec_altmode_exit() -> cros_typec_altmode_exit()
4. cros_typec_altmode_exit() attempts to acquire the mutex again
To prevent this, defer the `typec_altmode_exit()` call by scheduling
it rather than calling it directly from within the mutex-protected
context.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
comedi: das16m1: Fix bit shift out of bounds
When checking for a supported IRQ number, the following test is used:
/* only irqs 2, 3, 4, 5, 6, 7, 10, 11, 12, 14, and 15 are valid */
if ((1 << it->options[1]) & 0xdcfc) {
However, `it->options[i]` is an unchecked `int` value from userspace, so
the shift amount could be negative or out of bounds. Fix the test by
requiring `it->options[1]` to be within bounds before proceeding with
the original test.
Severity ?
No CVSS data available.

CVE-2025-38293 (GCVE-0-2025-38293)
Vulnerability from cvelistv5 – Published: 2025-07-10 07:42 – Updated: 2025-11-03 17:36

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix node corruption in ar->arvifs list
In current WLAN recovery code flow, ath11k_core_halt() only
reinitializes the "arvifs" list head. This will cause the
list node immediately following the list head to become an
invalid list node. Because the prev of that node still points
to the list head "arvifs", but the next of the list head "arvifs"
no longer points to that list node.
When a WLAN recovery occurs during the execution of a vif
removal, and it happens before the spin_lock_bh(&ar->data_lock)
in ath11k_mac_op_remove_interface(), list_del() will detect the
previously mentioned situation, thereby triggering a kernel panic.
The fix is to remove and reinitialize all vif list nodes from the
list head "arvifs" during WLAN halt. The reinitialization is to make
the list nodes valid, ensuring that the list_del() in
ath11k_mac_op_remove_interface() can execute normally.

CVE-2025-38350 (GCVE-0-2025-38350)
Vulnerability from cvelistv5 – Published: 2025-07-19 06:46 – Updated: 2025-11-03 17:37
VLAI?
EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: Always pass notifications when child class becomes empty
Certain classful qdiscs may invoke their classes' dequeue handler on an
enqueue operation. This may unexpectedly empty the child qdisc and thus
make an in-flight class passive via qlen_notify(). Most qdiscs do not
expect such behaviour at this point in time and may re-activate the
class eventually anyways which will lead to a use-after-free.
The referenced fix commit attempted to fix this behavior for the HFSC
case by moving the backlog accounting around, though this turned out to
be incomplete since the parent's parent may run into the issue too.
The following reproducer demonstrates this use-after-free:
tc qdisc add dev lo root handle 1: drr
tc filter add dev lo parent 1: basic classid 1:1
tc class add dev lo parent 1: classid 1:1 drr
tc qdisc add dev lo parent 1:1 handle 2: hfsc def 1
tc class add dev lo parent 2: classid 2:1 hfsc rt m1 8 d 1 m2 0
tc qdisc add dev lo parent 2:1 handle 3: netem
tc qdisc add dev lo parent 3:1 handle 4: blackhole
echo 1 | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888
tc class delete dev lo classid 1:1
echo 1 | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888
Since backlog accounting issues leading to a use-after-frees on stale
class pointers is a recurring pattern at this point, this patch takes
a different approach. Instead of trying to fix the accounting, the patch
ensures that qdisc_tree_reduce_backlog always calls qlen_notify when
the child qdisc is empty. This solves the problem because deletion of
qdiscs always involves a call to qdisc_reset() and / or
qdisc_purge_queue() which ultimately resets its qlen to 0 thus causing
the following qdisc_tree_reduce_backlog() to report to the parent. Note
that this may call qlen_notify on passive classes multiple times. This
is not a problem after the recent patch series that made all the
classful qdiscs qlen_notify() handlers idempotent.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: phy: mscc: Fix memory leak when using one step timestamping
Fix memory leak when running one-step timestamping. When running
one-step sync timestamping, the HW is configured to insert the TX time
into the frame, so there is no reason to keep the skb anymore. As in
this case the HW will never generate an interrupt to say that the frame
was timestamped, then the frame will never released.
Fix this by freeing the frame in case of one-step timestamping.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm: fix unconditional IO throttle caused by REQ_PREFLUSH
When a bio with REQ_PREFLUSH is submitted to dm, __send_empty_flush()
generates a flush_bio with REQ_OP_WRITE | REQ_PREFLUSH | REQ_SYNC,
which causes the flush_bio to be throttled by wbt_wait().
An example from v5.4, similar problem also exists in upstream:

After commit 2def2845cc33 ("xfs: don't allow log IO to be throttled"),
the metadata submitted by xlog_write_iclog() should not be throttled.
But due to the existence of the dm layer, throttling flush_bio indirectly
causes the metadata bio to be throttled.
Fix this by conditionally adding REQ_IDLE to flush_bio.bi_opf, which makes
wbt_should_throttle() return false to avoid wbt_wait().

Summary
In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Fix double invocation of bnxt_ulp_stop()/bnxt_ulp_start()
Before the commit under the Fixes tag below, bnxt_ulp_stop() and
bnxt_ulp_start() were always invoked in pairs. After that commit,
the new bnxt_ulp_restart() can be invoked after bnxt_ulp_stop()
has been called. This may result in the RoCE driver's aux driver
.suspend() method being invoked twice. The 2nd bnxt_re_suspend()
call will crash when it dereferences a NULL pointer:

Check the BNXT_EN_FLAG_ULP_STOPPED flag and do not proceed if the flag
is already set. This will preserve the original symmetrical
bnxt_ulp_stop() and bnxt_ulp_start().
Also, inside bnxt_ulp_start(), clear the BNXT_EN_FLAG_ULP_STOPPED
flag after taking the mutex to avoid any race condition. And for
symmetry, only proceed in bnxt_ulp_start() if the
BNXT_EN_FLAG_ULP_STOPPED is set.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFC: nci: uart: Set tty->disc_data only in success path
Setting tty->disc_data before opening the NCI device means we need to
clean it up on error paths. This also opens some short window if device
starts sending data, even before NCIUARTSETDRIVER IOCTL succeeded
(broken hardware?). Close the window by exposing tty->disc_data only on
the success path, when opening of the NCI device and try_module_get()
succeeds.
The code differs in error path in one aspect: tty->disc_data won't be
ever assigned thus NULL-ified. This however should not be relevant
difference, because of "tty->disc_data=NULL" in nci_uart_tty_open().
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: stmmac: make sure that ptp_rate is not 0 before configuring timestamping
The stmmac platform drivers that do not open-code the clk_ptp_rate value
after having retrieved the default one from the device-tree can end up
with 0 in clk_ptp_rate (as clk_get_rate can return 0). It will
eventually propagate up to PTP initialization when bringing up the
interface, leading to a divide by 0:
Division by zero in kernel.

Prevent this division by 0 by adding an explicit check and error log
about the actual issue. While at it, remove the same check from
stmmac_ptp_register, which then becomes duplicate

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_set_pipapo: prevent overflow in lookup table allocation
When calculating the lookup table size, ensure the following
multiplication does not overflow:
- desc->field_len[] maximum value is U8_MAX multiplied by
NFT_PIPAPO_GROUPS_PER_BYTE(f) that can be 2, worst case.
- NFT_PIPAPO_BUCKETS(f->bb) is 2^8, worst case.
- sizeof(unsigned long), from sizeof(*f->lt), lt in
struct nft_pipapo_field.
Then, use check_mul_overflow() to multiply by bucket size and then use
check_add_overflow() to the alignment for avx2 (if needed). Finally, add
lt_size_check_overflow() helper and use it to consolidate this.
While at it, replace leftover allocation using the GFP_KERNEL to
GFP_KERNEL_ACCOUNT for consistency, in pipapo_resize().

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: usb: lan78xx: fix WARN in __netif_napi_del_locked on disconnect
Remove redundant netif_napi_del() call from disconnect path.
A WARN may be triggered in __netif_napi_del_locked() during USB device
disconnect:
WARNING: CPU: 0 PID: 11 at net/core/dev.c:7417 __netif_napi_del_locked+0x2b4/0x350
This happens because netif_napi_del() is called in the disconnect path while
NAPI is still enabled. However, it is not necessary to call netif_napi_del()
explicitly, since unregister_netdev() will handle NAPI teardown automatically
and safely. Removing the redundant call avoids triggering the warning.

CVE-2025-38231 (GCVE-0-2025-38231)

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: Initialize ssc before laundromat_work to prevent NULL dereference
In nfs4_state_start_net(), laundromat_work may access nfsd_ssc through
nfs4_laundromat -> nfsd4_ssc_expire_umount. If nfsd_ssc isn't initialized,
this can cause NULL pointer dereference.
Normally the delayed start of laundromat_work allows sufficient time for
nfsd_ssc initialization to complete. However, when the kernel waits too
long for userspace responses (e.g. in nfs4_state_start_net ->
nfsd4_end_grace -> nfsd4_record_grace_done -> nfsd4_cld_grace_done ->
cld_pipe_upcall -> __cld_pipe_upcall -> wait_for_completion path), the
delayed work may start before nfsd_ssc initialization finishes.
Fix this by moving nfsd_ssc initialization before starting laundromat_work.

Summary
In the Linux kernel, the following vulnerability has been resolved:
regulator: gpio: Fix the out-of-bounds access to drvdata::gpiods
drvdata::gpiods is supposed to hold an array of 'gpio_desc' pointers. But
the memory is allocated for only one pointer. This will lead to
out-of-bounds access later in the code if 'config::ngpios' is > 1. So
fix the code to allocate enough memory to hold 'config::ngpios' of GPIO
descriptors.
While at it, also move the check for memory allocation failure to be below
the allocation to make it more readable.
Severity ?

Summary
In the Linux kernel, the following vulnerability has been resolved:
Squashfs: check return result of sb_min_blocksize
Syzkaller reports an "UBSAN: shift-out-of-bounds in squashfs_bio_read" bug.
Syzkaller forks multiple processes which after mounting the Squashfs
filesystem, issues an ioctl("/dev/loop0", LOOP_SET_BLOCK_SIZE, 0x8000).
Now if this ioctl occurs at the same time another process is in the
process of mounting a Squashfs filesystem on /dev/loop0, the failure
occurs. When this happens the following code in squashfs_fill_super()
fails.
----
msblk->devblksize = sb_min_blocksize(sb, SQUASHFS_DEVBLK_SIZE);
msblk->devblksize_log2 = ffz(~msblk->devblksize);
----
sb_min_blocksize() returns 0, which means msblk->devblksize is set to 0.
As a result, ffz(~msblk->devblksize) returns 64, and msblk->devblksize_log2
is set to 64.
This subsequently causes the
UBSAN: shift-out-of-bounds in fs/squashfs/block.c:195:36
shift exponent 64 is too large for 64-bit type 'u64' (aka
'unsigned long long')
This commit adds a check for a 0 return by sb_min_blocksize().
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_core: Fix use-after-free in vhci_flush()
syzbot reported use-after-free in vhci_flush() without repro. [0]
From the splat, a thread close()d a vhci file descriptor while
its device was being used by iotcl() on another thread.
Once the last fd refcnt is released, vhci_release() calls
hci_unregister_dev(), hci_free_dev(), and kfree() for struct
vhci_data, which is set to hci_dev->dev->driver_data.
The problem is that there is no synchronisation after unlinking
hdev from hci_dev_list in hci_unregister_dev(). There might be
another thread still accessing the hdev which was fetched before
the unlink operation.
We can use SRCU for such synchronisation.
Let's run hci_dev_reset() under SRCU and wait for its completion
in hci_unregister_dev().
Another option would be to restore hci_dev->destruct(), which was
removed in commit 587ae086f6e4 ("Bluetooth: Remove unused
hci-destruct cb"). However, this would not be a good solution, as
we should not run hci_unregister_dev() while there are in-flight
ioctl() requests, which could lead to another data-race KCSAN splat.
Note that other drivers seem to have the same problem, for exmaple,
virtbt_remove().

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Load DR6 with guest value only before entering .vcpu_run() loop
Move the conditional loading of hardware DR6 with the guest's DR6 value
out of the core .vcpu_run() loop to fix a bug where KVM can load hardware
with a stale vcpu->arch.dr6.
When the guest accesses a DR and host userspace isn't debugging the guest,
KVM disables DR interception and loads the guest's values into hardware on
VM-Enter and saves them on VM-Exit. This allows the guest to access DRs
at will, e.g. so that a sequence of DR accesses to configure a breakpoint
only generates one VM-Exit.
For DR0-DR3, the logic/behavior is identical between VMX and SVM, and also
identical between KVM_DEBUGREG_BP_ENABLED (userspace debugging the guest)
and KVM_DEBUGREG_WONT_EXIT (guest using DRs), and so KVM handles loading
DR0-DR3 in common code, _outside_ of the core kvm_x86_ops.vcpu_run() loop.
But for DR6, the guest's value doesn't need to be loaded into hardware for
KVM_DEBUGREG_BP_ENABLED, and SVM provides a dedicated VMCB field whereas
VMX requires software to manually load the guest value, and so loading the
guest's value into DR6 is handled by {svm,vmx}_vcpu_run(), i.e. is done
_inside_ the core run loop.
Unfortunately, saving the guest values on VM-Exit is initiated by common
x86, again outside of the core run loop. If the guest modifies DR6 (in
hardware, when DR interception is disabled), and then the next VM-Exit is
a fastpath VM-Exit, KVM will reload hardware DR6 with vcpu->arch.dr6 and
clobber the guest's actual value.
The bug shows up primarily with nested VMX because KVM handles the VMX
preemption timer in the fastpath, and the window between hardware DR6
being modified (in guest context) and DR6 being read by guest software is
orders of magnitude larger in a nested setup. E.g. in non-nested, the
VMX preemption timer would need to fire precisely between #DB injection
and the #DB handler's read of DR6, whereas with a KVM-on-KVM setup, the
window where hardware DR6 is "dirty" extends all the way from L1 writing
DR6 to VMRESUME (in L1).

E.g. in non-nested, the\nVMX preemption timer would need to fire precisely between #DB injection\nand the #DB handler\u0027s read of DR6, whereas with a KVM-on-KVM setup, the\nwindow where hardware DR6 is \"dirty\" extends all the way from L1 writing\nDR6 to VMRESUME (in L1).\n\n L1\u0027s view:\n ==========\n \u003cL1 disables DR interception\u003e\n CPU 0/KVM-7289 [023] d.... 2925.640961: kvm_entry: vcpu 0\n A: L1 Writes DR6\n CPU 0/KVM-7289 [023] d.... 2925.640963: \u003chack\u003e: Set DRs, DR6 = 0xffff0ff1\n\n B: CPU 0/KVM-7289 [023] d.... 2925.640967: kvm_exit: vcpu 0 reason EXTERNAL_INTERRUPT intr_info 0x800000ec\n\n D: L1 reads DR6, arch.dr6 = 0\n CPU 0/KVM-7289 [023] d.... 2925.640969: \u003chack\u003e: Sync DRs, DR6 = 0xffff0ff0\n\n CPU 0/KVM-7289 [023] d.... 2925.640976: kvm_entry: vcpu 0\n L2 reads DR6, L1 disables DR interception\n CPU 0/KVM-7289 [023] d.... 2925.640980: kvm_exit: vcpu 0 reason DR_ACCESS info1 0x0000000000000216\n CPU 0/KVM-7289 [023] d.... 2925.640983: kvm_entry: vcpu 0\n\n CPU 0/KVM-7289 [023] d.... 2925.640983: \u003chack\u003e: Set DRs, DR6 = 0xffff0ff0\n\n L2 detects failure\n CPU 0/KVM-7289 [023] d.... 2925.640987: kvm_exit: vcpu 0 reason HLT\n L1 reads DR6 (confirms failure)\n CPU 0/KVM-7289 [023] d.... 2925.640990: \u003chack\u003e: Sync DRs, DR6 = 0xffff0ff0\n\n L0\u0027s view:\n ==========\n L2 reads DR6, arch.dr6 = 0\n CPU 23/KVM-5046 [001] d.... 3410.005610: kvm_exit: vcpu 23 reason DR_ACCESS info1 0x0000000000000216\n CPU 23/KVM-5046 [001] ..... 3410.005610: kvm_nested_vmexit: vcpu 23 reason DR_ACCESS info1 0x0000000000000216\n\n L2 =\u003e L1 nested VM-Exit\n CPU 23/KVM-5046 [001] ..... 3410.005610: kvm_nested_vmexit_inject: reason: DR_ACCESS ext_inf1: 0x0000000000000216\n\n CPU 23/KVM-5046 [001] d.... 3410.005610: kvm_entry: vcpu 23\n CPU 23/KVM-5046 [001] d.... 3410.005611: kvm_exit: vcpu 23 reason VMREAD\n CPU 23/KVM-5046 [001] d.... 3410.005611: kvm_entry: vcpu 23\n CPU 23/KVM-5046 [001] d.... 3410.\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/gpu: Fix crash when throttling GPU immediately during boot
There is a small chance that the GPU is already hot during boot. In that
case, the call to of_devfreq_cooling_register() will immediately try to
apply devfreq cooling, as seen in the following crash:
Unable to handle kernel paging request at virtual address 0000000000014110
pc : a6xx_gpu_busy+0x1c/0x58 [msm]
lr : msm_devfreq_get_dev_status+0xbc/0x140 [msm]

adreno_bind+0x2a8/0x33c [msm]
...
At this point we haven't initialized the GMU at all yet, so we cannot read
the GMU registers inside a6xx_gpu_busy(). A similar issue was fixed before
in commit 6694482a70e9 ("drm/msm: Avoid unclocked GMU register access in
6xx gpu_busy"): msm_devfreq_init() does call devfreq_suspend_device(), but
unlike msm_devfreq_suspend(), it doesn't set the df->suspended flag
accordingly. This means the df->suspended flag does not match the actual
devfreq state after initialization and msm_devfreq_get_dev_status() will
end up accessing GMU registers, causing the crash.
Fix this by setting df->suspended correctly during initialization.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/gt: Fix timeline left held on VMA alloc error
The following error has been reported sporadically by CI when a test
unbinds the i915 driver on a ring submission platform:

...
Closer analysis of CI results history has revealed a dependency of the
error on a few IGT tests, namely:
- igt@api_intel_allocator@fork-simple-stress-signal,
- igt@api_intel_allocator@two-level-inception-interruptible,
- igt@gem_linear_blits@interruptible,
- igt@prime_mmap_coherency@ioctl-errors,
which invisibly trigger the issue, then exhibited with first driver unbind
attempt.
All of the above tests perform actions which are actively interrupted with
signals. Further debugging has allowed to narrow that scope down to
DRM_IOCTL_I915_GEM_EXECBUFFER2, and ring_context_alloc(), specific to ring
submission, in particular.
If successful then that function, or its execlists or GuC submission
equivalent, is supposed to be called only once per GEM context engine,
followed by raise of a flag that prevents the function from being called
again. The function is expected to unwind its internal errors itself, so
it may be safely called once more after it returns an error.
In case of ring submission, the function first gets a reference to the
engine's legacy timeline and then allocates a VMA. If the VMA allocation
fails, e.g. when i915_vma_instance() called from inside is interrupted
with a signal, then ring_context_alloc() fails, leaving the timeline held
referenced. On next I915_GEM_EXECBUFFER2 IOCTL, another reference to the
timeline is got, and only that last one is put on successful completion.
As a consequence, the legacy timeline, with its underlying engine status
page's VMA object, is still held and not released on driver unbind.
Get the legacy timeline only after successful allocation of the context
engine's VMA.
v2: Add a note on other submission methods (Krzysztof Karas):
Both execlists and GuC submission use lrc_alloc() which seems free
from a similar issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
eventpoll: don't decrement ep refcount while still holding the ep mutex
Jann Horn points out that epoll is decrementing the ep refcount and then
doing a
mutex_unlock(&ep->mtx);
afterwards. That's very wrong, because it can lead to a use-after-free.
That pattern is actually fine for the very last reference, because the
code in question will delay the actual call to "ep_free(ep)" until after
it has unlocked the mutex.
But it's wrong for the much subtler "next to last" case when somebody
*else* may also be dropping their reference and free the ep while we're
still using the mutex.
Note that this is true even if that other user is also using the same ep
mutex: mutexes, unlike spinlocks, can not be used for object ownership,
even if they guarantee mutual exclusion.
A mutex "unlock" operation is not atomic, and as one user is still
accessing the mutex as part of unlocking it, another user can come in
and get the now released mutex and free the data structure while the
first user is still cleaning up.
See our mutex documentation in Documentation/locking/mutex-design.rst,
in particular the section [1] about semantics:
"mutex_unlock() may access the mutex structure even after it has
internally released the lock already - so it's not safe for
another context to acquire the mutex and assume that the
mutex_unlock() context is not using the structure anymore"
So if we drop our ep ref before the mutex unlock, but we weren't the
last one, we may then unlock the mutex, another user comes in, drops
_their_ reference and releases the 'ep' as it now has no users - all
while the mutex_unlock() is still accessing it.
Fix this by simply moving the ep refcount dropping to outside the mutex:
the refcount itself is atomic, and doesn't need mutex protection (that's
the whole _point_ of refcounts: unlike mutexes, they are inherently
about object lifetimes).
Severity ?

Device setup:
netdevsim0 (down)
^ ^
bond netdevsim1.100@netdevsim1 allmulticast=on (down)
When we enslave the lower device (netdevsim0) which has a vlan, we
propagate vlan's allmuti/promisc flags during ndo_open. This causes
(re)locking on of the real_dev.
Propagate allmulti/promisc on flags change, not on the open. There
is a slight semantics change that vlans that are down now propagate
the flags, but this seems unlikely to result in the real issues.
Reproducer:
echo 0 1 > /sys/bus/netdevsim/new_device
dev_path=$(ls -d /sys/bus/netdevsim/devices/netdevsim0/net/*)
dev=$(echo $dev_path | rev | cut -d/ -f1 | rev)
ip link set dev $dev name netdevsim0
ip link set dev netdevsim0 up
ip link add link netdevsim0 name netdevsim0.100 type vlan id 100
ip link set dev netdevsim0.100 allm

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: do not BUG_ON() when freeing tree block after error
When freeing a tree block, at btrfs_free_tree_block(), if we fail to
create a delayed reference we don't deal with the error and just do a
BUG_ON(). The error most likely to happen is -ENOMEM, and we have a
comment mentioning that only -ENOMEM can happen, but that is not true,
because in case qgroups are enabled any error returned from
btrfs_qgroup_trace_extent_post() (can be -EUCLEAN or anything returned
from btrfs_search_slot() for example) can be propagated back to
btrfs_free_tree_block().
So stop doing a BUG_ON() and return the error to the callers and make
them abort the transaction to prevent leaking space. Syzbot was
triggering this, likely due to memory allocation failure injection.
Severity ?

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Fix error flow upon firmware failure for RQ destruction
Upon RQ destruction if the firmware command fails which is the
last resource to be destroyed some SW resources were already cleaned
regardless of the failure.
Now properly rollback the object to its original state upon such failure.
In order to avoid a use-after free in case someone tries to destroy the
object again, which results in the following kernel trace:
refcount_t: underflow; use-after-free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/sgx: Prevent attempts to reclaim poisoned pages
TL;DR: SGX page reclaim touches the page to copy its contents to
secondary storage. SGX instructions do not gracefully handle machine
checks. Despite this, the existing SGX code will try to reclaim pages
that it _knows_ are poisoned. Avoid even trying to reclaim poisoned pages.
The longer story:
Pages used by an enclave only get epc_page->poison set in
arch_memory_failure() but they currently stay on sgx_active_page_list until
sgx_encl_release(), with the SGX_EPC_PAGE_RECLAIMER_TRACKED flag untouched.
epc_page->poison is not checked in the reclaimer logic meaning that, if other
conditions are met, an attempt will be made to reclaim an EPC page that was
poisoned. This is bad because 1. we don't want that page to end up added
to another enclave and 2. it is likely to cause one core to shut down
and the kernel to panic.
Specifically, reclaiming uses microcode operations including "EWB" which
accesses the EPC page contents to encrypt and write them out to non-SGX
memory. Those operations cannot handle MCEs in their accesses other than
by putting the executing core into a special shutdown state (affecting
both threads with HT.) The kernel will subsequently panic on the
remaining cores seeing the core didn't enter MCE handler(s) in time.
Call sgx_unmark_page_reclaimable() to remove the affected EPC page from
sgx_active_page_list on memory error to stop it being considered for
reclaiming.
Testing epc_page->poison in sgx_reclaim_pages() would also work but I assume
it's better to add code in the less likely paths.
The affected EPC page is not added to &node->sgx_poison_page_list until
later in sgx_encl_release()->sgx_free_epc_page() when it is EREMOVEd.
Membership on other lists doesn't change to avoid changing any of the
lists' semantics except for sgx_active_page_list. There's a "TBD" comment
in arch_memory_failure() about pre-emptive actions, the goal here is not
to address everything that it may imply.
This also doesn't completely close the time window when a memory error
notification will be fatal (for a not previously poisoned EPC page) --
the MCE can happen after sgx_reclaim_pages() has selected its candidates
or even *inside* a microcode operation (actually easy to trigger due to
the amount of time spent in them.)
The spinlock in sgx_unmark_page_reclaimable() is safe because
memory_failure() runs in process context and no spinlocks are held,
explicitly noted in a mm/memory-failure.c comment.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nx86/sgx: Prevent attempts to reclaim poisoned pages\n\nTL;DR: SGX page reclaim touches the page to copy its contents to\nsecondary storage. SGX instructions do not gracefully handle machine\nchecks. Despite this, the existing SGX code will try to reclaim pages\nthat it _knows_ are poisoned. Avoid even trying to reclaim poisoned pages.\n\nThe longer story:\n\nPages used by an enclave only get epc_page-\u003epoison set in\narch_memory_failure() but they currently stay on sgx_active_page_list until\nsgx_encl_release(), with the SGX_EPC_PAGE_RECLAIMER_TRACKED flag untouched.\n\nepc_page-\u003epoison is not checked in the reclaimer logic meaning that, if other\nconditions are met, an attempt will be made to reclaim an EPC page that was\npoisoned. This is bad because 1. we don\u0027t want that page to end up added\nto another enclave and 2. it is likely to cause one core to shut down\nand the kernel to panic.\n\nSpecifically, reclaiming uses microcode operations including \"EWB\" which\naccesses the EPC page contents to encrypt and write them out to non-SGX\nmemory. Those operations cannot handle MCEs in their accesses other than\nby putting the executing core into a special shutdown state (affecting\nboth threads with HT.) The kernel will subsequently panic on the\nremaining cores seeing the core didn\u0027t enter MCE handler(s) in time.\n\nCall sgx_unmark_page_reclaimable() to remove the affected EPC page from\nsgx_active_page_list on memory error to stop it being considered for\nreclaiming.\n\nTesting epc_page-\u003epoison in sgx_reclaim_pages() would also work but I assume\nit\u0027s better to add code in the less likely paths.\n\nThe affected EPC page is not added to \u0026node-\u003esgx_poison_page_list until\nlater in sgx_encl_release()-\u003esgx_free_epc_page() when it is EREMOVEd.\nMembership on other lists doesn\u0027t change to avoid changing any of the\nlists\u0027 semantics except for sgx_active_page_list. There\u0027s a \"TBD\" comment\nin arch_memory_failure() about pre-emptive actions, the goal here is not\nto address everything that it may imply.\n\nThis also doesn\u0027t completely close the time window when a memory error\nnotification will be fatal (for a not previously poisoned EPC page) --\nthe MCE can happen after sgx_reclaim_pages() has selected its candidates\nor even *inside* a microcode operation (actually easy to trigger due to\nthe amount of time spent in them.)\n\nThe spinlock in sgx_unmark_page_reclaimable() is safe because\nmemory_failure() runs in process context and no spinlocks are held,\nexplicitly noted in a mm/memory-failure.c comment."

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs: export anon_inode_make_secure_inode() and fix secretmem LSM bypass
Export anon_inode_make_secure_inode() to allow KVM guest_memfd to create
anonymous inodes with proper security context. This replaces the current
pattern of calling alloc_anon_inode() followed by
inode_init_security_anon() for creating security context manually.
This change also fixes a security regression in secretmem where the
S_PRIVATE flag was not cleared after alloc_anon_inode(), causing
LSM/SELinux checks to be bypassed for secretmem file descriptors.
As guest_memfd currently resides in the KVM module, we need to export this
symbol for use outside the core kernel. In the future, guest_memfd might be
moved to core-mm, at which point the symbols no longer would have to be
exported. When/if that happens is still unclear.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
comedi: das6402: Fix bit shift out of bounds
When checking for a supported IRQ number, the following test is used:
/* IRQs 2,3,5,6,7, 10,11,15 are valid for "enhanced" mode */
if ((1 << it->options[1]) & 0x8cec) {
However, `it->options[i]` is an unchecked `int` value from userspace, so
the shift amount could be negative or out of bounds. Fix the test by
requiring `it->options[1]` to be within bounds before proceeding with
the original test. Valid `it->options[1]` values that select the IRQ
will be in the range [1,15]. The value 0 explicitly disables the use of
interrupts.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: accel: fxls8962af: Fix use after free in fxls8962af_fifo_flush
fxls8962af_fifo_flush() uses indio_dev->active_scan_mask (with
iio_for_each_active_channel()) without making sure the indio_dev
stays in buffer mode.
There is a race if indio_dev exits buffer mode in the middle of the
interrupt that flushes the fifo. Fix this by calling
synchronize_irq() to ensure that no interrupt is currently running when
disabling buffer mode.
Unable to handle kernel NULL pointer dereference at virtual address 00000000 when read

CVE-2025-38108 (GCVE-0-2025-38108)

Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: red: fix a race in __red_change()
Gerrard Tai reported a race condition in RED, whenever SFQ perturb timer
fires at the wrong time.
The race is as follows:
CPU 0 CPU 1
[1]: lock root
[2]: qdisc_tree_flush_backlog()
[3]: unlock root
|
| [5]: lock root
| [6]: rehash
| [7]: qdisc_tree_reduce_backlog()
|
[4]: qdisc_put()
This can be abused to underflow a parent's qlen.
Calling qdisc_purge_queue() instead of qdisc_tree_flush_backlog()
should fix the race, because all packets will be purged from the qdisc
before releasing the lock.
Severity ?

Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: sch_sfq: reject invalid perturb period
Gerrard Tai reported that SFQ perturb_period has no range check yet,
and this can be used to trigger a race condition fixed in a separate patch.
We want to make sure ctl->perturb_period * HZ will not overflow
and is positive.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: CPPC: Fix NULL pointer dereference when nosmp is used
With nosmp in cmdline, other CPUs are not brought up, leaving
their cpc_desc_ptr NULL. CPU0's iteration via for_each_possible_cpu()
dereferences these NULL pointers, causing panic.
Panic backtrace:
[ 0.401123] Unable to handle kernel NULL pointer dereference at virtual address 00000000000000b8
...
[ 0.403255] [<ffffffff809a5818>] cppc_allow_fast_switch+0x6a/0xd4
...
Kernel panic - not syncing: Attempted to kill init!

CVE-2025-38436 (GCVE-0-2025-38436)

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/scheduler: signal scheduled fence when kill job
When an entity from application B is killed, drm_sched_entity_kill()
removes all jobs belonging to that entity through
drm_sched_entity_kill_jobs_work(). If application A's job depends on a
scheduled fence from application B's job, and that fence is not properly
signaled during the killing process, application A's dependency cannot be
cleared.
This leads to application A hanging indefinitely while waiting for a
dependency that will never be resolved. Fix this issue by ensuring that
scheduled fences are properly signaled when an entity is killed, allowing
dependent applications to continue execution.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: SVM: Reject SEV{-ES} intra host migration if vCPU creation is in-flight
Reject migration of SEV{-ES} state if either the source or destination VM
is actively creating a vCPU, i.e. if kvm_vm_ioctl_create_vcpu() is in the
section between incrementing created_vcpus and online_vcpus. The bulk of
vCPU creation runs _outside_ of kvm->lock to allow creating multiple vCPUs
in parallel, and so sev_info.es_active can get toggled from false=>true in
the destination VM after (or during) svm_vcpu_create(), resulting in an
SEV{-ES} VM effectively having a non-SEV{-ES} vCPU.
The issue manifests most visibly as a crash when trying to free a vCPU's
NULL VMSA page in an SEV-ES VM, but any number of things can go wrong.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: fix Tx scheduler error handling in XDP callback
When the XDP program is loaded, the XDP callback adds new Tx queues.
This means that the callback must update the Tx scheduler with the new
queue number. In the event of a Tx scheduler failure, the XDP callback
should also fail and roll back any changes previously made for XDP
preparation.
The previous implementation had a bug that not all changes made by the
XDP callback were rolled back. This caused the crash with the following
call trace:
[ +9.549584] ice 0000:ca:00.0: Failed VSI LAN queue config for XDP, error: -5

Fix this by performing the missing unmapping of XDP queues from
q_vectors and setting the XDP rings pointer back to NULL after all those
queues are released.
Also, add an immediate exit from the XDP callback in case of ring
preparation failure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: tipc: fix refcount warning in tipc_aead_encrypt
syzbot reported a refcount warning [1] caused by calling get_net() on
a network namespace that is being destroyed (refcount=0). This happens
when a TIPC discovery timer fires during network namespace cleanup.
The recently added get_net() call in commit e279024617134 ("net/tipc:
fix slab-use-after-free Read in tipc_aead_encrypt_done") attempts to
hold a reference to the network namespace. However, if the namespace
is already being destroyed, its refcount might be zero, leading to the
use-after-free warning.
Replace get_net() with maybe_get_net(), which safely checks if the
refcount is non-zero before incrementing it. If the namespace is being
destroyed, return -ENODEV early, after releasing the bearer reference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bridge: mcast: Fix use-after-free during router port configuration
The bridge maintains a global list of ports behind which a multicast
router resides. The list is consulted during forwarding to ensure
multicast packets are forwarded to these ports even if the ports are not
member in the matching MDB entry.
When per-VLAN multicast snooping is enabled, the per-port multicast
context is disabled on each port and the port is removed from the global
router port list:
# ip link add name br1 up type bridge vlan_filtering 1 mcast_snooping 1
# ip link add name dummy1 up master br1 type dummy
# ip link set dev dummy1 type bridge_slave mcast_router 2
$ bridge -d mdb show | grep router
router ports on br1: dummy1
# ip link set dev br1 type bridge mcast_vlan_snooping 1
$ bridge -d mdb show | grep router
However, the port can be re-added to the global list even when per-VLAN
multicast snooping is enabled:
# ip link set dev dummy1 type bridge_slave mcast_router 0
# ip link set dev dummy1 type bridge_slave mcast_router 2
$ bridge -d mdb show | grep router
router ports on br1: dummy1
Since commit 4b30ae9adb04 ("net: bridge: mcast: re-implement
br_multicast_{enable, disable}_port functions"), when per-VLAN multicast
snooping is enabled, multicast disablement on a port will disable the
per-{port, VLAN} multicast contexts and not the per-port one. As a
result, a port will remain in the global router port list even after it
is deleted. This will lead to a use-after-free [1] when the list is
traversed (when adding a new port to the list, for example):
# ip link del dev dummy1
# ip link add name dummy2 up master br1 type dummy
# ip link set dev dummy2 type bridge_slave mcast_router 2
Similarly, stale entries can also be found in the per-VLAN router port
list. When per-VLAN multicast snooping is disabled, the per-{port, VLAN}
contexts are disabled on each port and the port is removed from the
per-VLAN router port list:
# ip link add name br1 up type bridge vlan_filtering 1 mcast_snooping 1 mcast_vlan_snooping 1
# ip link add name dummy1 up master br1 type dummy
# bridge vlan add vid 2 dev dummy1
# bridge vlan global set vid 2 dev br1 mcast_snooping 1
# bridge vlan set vid 2 dev dummy1 mcast_router 2
$ bridge vlan global show dev br1 vid 2 | grep router
router ports: dummy1
# ip link set dev br1 type bridge mcast_vlan_snooping 0
$ bridge vlan global show dev br1 vid 2 | grep router
However, the port can be re-added to the per-VLAN list even when
per-VLAN multicast snooping is disabled:
# bridge vlan set vid 2 dev dummy1 mcast_router 0
# bridge vlan set vid 2 dev dummy1 mcast_router 2
$ bridge vlan global show dev br1 vid 2 | grep router
router ports: dummy1
When the VLAN is deleted from the port, the per-{port, VLAN} multicast
context will not be disabled since multicast snooping is not enabled
on the VLAN. As a result, the port will remain in the per-VLAN router
port list even after it is no longer member in the VLAN. This will lead
to a use-after-free [2] when the list is traversed (when adding a new
port to the list, for example):
# ip link add name dummy2 up master br1 type dummy
# bridge vlan add vid 2 dev dummy2
# bridge vlan del vid 2 dev dummy1
# bridge vlan set vid 2 dev dummy2 mcast_router 2
Fix these issues by removing the port from the relevant (global or
per-VLAN) router port list in br_multicast_port_ctx_deinit(). The
function is invoked during port deletion with the per-port multicast
context and during VLAN deletion with the per-{port, VLAN} multicast
context.
Note that deleting the multicast router timer is not enough as it only
takes care of the temporary multicast router states (1 or 3) and not the
permanent one (2).

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: chipidea: udc: disconnect/reconnect from host when do suspend/resume
Shawn and John reported a hang issue during system suspend as below:
- USB gadget is enabled as Ethernet
- There is data transfer over USB Ethernet (scp a big file between host
and device)
- Device is going in/out suspend (echo mem > /sys/power/state)
The root cause is the USB device controller is suspended but the USB bus
is still active which caused the USB host continues to transfer data with
device and the device continues to queue USB requests (in this case, a
delayed TCP ACK packet trigger the issue) after controller is suspended,
however the USB controller clock is already gated off. Then if udc driver
access registers after that point, the system will hang.
The correct way to avoid such issue is to disconnect device from host when
the USB bus is not at suspend state. Then the host will receive disconnect
event and stop data transfer in time. To continue make USB gadget device
work after system resume, this will reconnect device automatically.
To make usb wakeup work if USB bus is already at suspend state, this will
keep connection for it only when USB device controller has enabled wakeup
capability.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/fred: Fix system hang during S4 resume with FRED enabled
Upon a wakeup from S4, the restore kernel starts and initializes the
FRED MSRs as needed from its perspective. It then loads a hibernation
image, including the image kernel, and attempts to load image pages
directly into their original page frames used before hibernation unless
those frames are currently in use. Once all pages are moved to their
original locations, it jumps to a "trampoline" page in the image kernel.
At this point, the image kernel takes control, but the FRED MSRs still
contain values set by the restore kernel, which may differ from those
set by the image kernel before hibernation. Therefore, the image kernel
must ensure the FRED MSRs have the same values as before hibernation.
Since these values depend only on the location of the kernel text and
data, they can be recomputed from scratch.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: fnic: Fix crash in fnic_wq_cmpl_handler when FDMI times out
When both the RHBA and RPA FDMI requests time out, fnic reuses a frame to
send ABTS for each of them. On send completion, this causes an attempt to
free the same frame twice that leads to a crash.
Fix crash by allocating separate frames for RHBA and RPA, and modify ABTS
logic accordingly.
Tested by checking MDS for FDMI information.
Tested by using instrumented driver to:
- Drop PLOGI response
- Drop RHBA response
- Drop RPA response
- Drop RHBA and RPA response
- Drop PLOGI response + ABTS response
- Drop RHBA response + ABTS response
- Drop RPA response + ABTS response
- Drop RHBA and RPA response + ABTS response for both of them
Severity ?
No CVSS data available.

CVE-2025-38290 (GCVE-0-2025-38290)
Vulnerability from cvelistv5 – Published: 2025-07-10 07:42 – Updated: 2025-07-28 04:17

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix node corruption in ar->arvifs list
In current WLAN recovery code flow, ath12k_core_halt() only reinitializes
the "arvifs" list head. This will cause the list node immediately following
the list head to become an invalid list node. Because the prev of that node
still points to the list head "arvifs", but the next of the list head
"arvifs" no longer points to that list node.
When a WLAN recovery occurs during the execution of a vif removal, and it
happens before the spin_lock_bh(&ar->data_lock) in
ath12k_mac_vdev_delete(), list_del() will detect the previously mentioned
situation, thereby triggering a kernel panic.
The fix is to remove and reinitialize all vif list nodes from the list head
"arvifs" during WLAN halt. The reinitialization is to make the list nodes
valid, ensuring that the list_del() in ath12k_mac_vdev_delete() can execute
normally.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Process deferred GGTT node removals on device unwind
While we are indirectly draining our dedicated workqueue ggtt->wq
that we use to complete asynchronous removal of some GGTT nodes,
this happends as part of the managed-drm unwinding (ggtt_fini_early),
which could be later then manage-device unwinding, where we could
already unmap our MMIO/GMS mapping (mmio_fini).
This was recently observed during unsuccessful VF initialization:
[ ] xe 0000:00:02.1: probe with driver xe failed with error -62
[ ] xe 0000:00:02.1: DEVRES REL ffff88811e747340 __xe_bo_unpin_map_no_vm (16 bytes)

[ ] xe 0000:00:02.1: DEVRES REL ffff88811e746b40 devm_drm_dev_init_release (16 bytes)
[ ] xe 0000:00:02.1: [drm:drm_managed_release] drmres release begin
[ ] xe 0000:00:02.1: [drm:drm_managed_release] REL ffff88810ef81640 __fini_relay (8 bytes)

[ ] xe 0000:00:02.1: [drm:drm_managed_release] REL ffff88810ef80140 ggtt_fini_early (8 bytes)
and this was leading to:
[ ] BUG: unable to handle page fault for address: ffffc900058162a0
[ ] #PF: supervisor write access in kernel mode
[ ] #PF: error_code(0x0002) - not-present page

Add managed-device action that will explicitly drain the workqueue
with all pending node removals prior to releasing MMIO/GSM mapping.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_set_pipapo: fix initial map fill
The initial buffer has to be inited to all-ones, but it must restrict
it to the size of the first field, not the total field size.
After each round in the map search step, the result and the fill map
are swapped, so if we have a set where f->bsize of the first element
is smaller than m->bsize_max, those one-bits are leaked into future
rounds result map.
This makes pipapo find an incorrect matching results for sets where
first field size is not the largest.
Followup patch adds a test case to nft_concat_range.sh selftest script.
Thanks to Stefano Brivio for pointing out that we need to zero out
the remainder explicitly, only correcting memset() argument isn't enough.

Summary
In the Linux kernel, the following vulnerability has been resolved:
comedi: Fix initialization of data for instructions that write to subdevice
Some Comedi subdevice instruction handlers are known to access
instruction data elements beyond the first `insn->n` elements in some
cases. The `do_insn_ioctl()` and `do_insnlist_ioctl()` functions
allocate at least `MIN_SAMPLES` (16) data elements to deal with this,
but they do not initialize all of that. For Comedi instruction codes
that write to the subdevice, the first `insn->n` data elements are
copied from user-space, but the remaining elements are left
uninitialized. That could be a problem if the subdevice instruction
handler reads the uninitialized data. Ensure that the first
`MIN_SAMPLES` elements are initialized before calling these instruction
handlers, filling the uncopied elements with 0. For
`do_insnlist_ioctl()`, the same data buffer elements are used for
handling a list of instructions, so ensure the first `MIN_SAMPLES`
elements are initialized for each instruction that writes to the
subdevice.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers/rapidio/rio_cm.c: prevent possible heap overwrite
In
riocm_cdev_ioctl(RIO_CM_CHAN_SEND)
-> cm_chan_msg_send()
-> riocm_ch_send()
cm_chan_msg_send() checks that userspace didn't send too much data but
riocm_ch_send() failed to check that userspace sent sufficient data. The
result is that riocm_ch_send() can write to fields in the rio_ch_chan_hdr
which were outside the bounds of the space which cm_chan_msg_send()
allocated.
Address this by teaching riocm_ch_send() to check that the entire
rio_ch_chan_hdr was copied in from userspace.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: Do not double dequeue a configuration request
Some of our devices crash in tb_cfg_request_dequeue():
general protection fault, probably for non-canonical address 0xdead000000000122
CPU: 6 PID: 91007 Comm: kworker/6:2 Tainted: G U W 6.6.65
RIP: 0010:tb_cfg_request_dequeue+0x2d/0xa0
Call Trace:
<TASK>
? tb_cfg_request_dequeue+0x2d/0xa0
tb_cfg_request_work+0x33/0x80
worker_thread+0x386/0x8f0
kthread+0xed/0x110
ret_from_fork+0x38/0x50
ret_from_fork_asm+0x1b/0x30
The circumstances are unclear, however, the theory is that
tb_cfg_request_work() can be scheduled twice for a request:
first time via frame.callback from ring_work() and second
time from tb_cfg_request(). Both times kworkers will execute
tb_cfg_request_dequeue(), which results in double list_del()
from the ctl->request_queue (the list poison deference hints
at it: 0xdead000000000122).
Do not dequeue requests that don't have TB_CFG_REQUEST_ACTIVE
bit set.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ptp: remove ptp->n_vclocks check logic in ptp_vclock_in_use()
There is no disagreement that we should check both ptp->is_virtual_clock
and ptp->n_vclocks to check if the ptp virtual clock is in use.
However, when we acquire ptp->n_vclocks_mux to read ptp->n_vclocks in
ptp_vclock_in_use(), we observe a recursive lock in the call trace
starting from n_vclocks_store().
============================================
WARNING: possible recursive locking detected
6.15.0-rc6 #1 Not tainted
--------------------------------------------
syz.0.1540/13807 is trying to acquire lock:
ffff888035a24868 (&ptp->n_vclocks_mux){+.+.}-{4:4}, at:
ptp_vclock_in_use drivers/ptp/ptp_private.h:103 [inline]
ffff888035a24868 (&ptp->n_vclocks_mux){+.+.}-{4:4}, at:
ptp_clock_unregister+0x21/0x250 drivers/ptp/ptp_clock.c:415
but task is already holding lock:
ffff888030704868 (&ptp->n_vclocks_mux){+.+.}-{4:4}, at:
n_vclocks_store+0xf1/0x6d0 drivers/ptp/ptp_sysfs.c:215
other info that might help us debug this:
Possible unsafe locking scenario:
CPU0
----
lock(&ptp->n_vclocks_mux);
lock(&ptp->n_vclocks_mux);
*** DEADLOCK ***
....
============================================
The best way to solve this is to remove the logic that checks
ptp->n_vclocks in ptp_vclock_in_use().
The reason why this is appropriate is that any path that uses
ptp->n_vclocks must unconditionally check if ptp->n_vclocks is greater
than 0 before unregistering vclocks, and all functions are already
written this way. And in the function that uses ptp->n_vclocks, we
already get ptp->n_vclocks_mux before unregistering vclocks.
Therefore, we need to remove the redundant check for ptp->n_vclocks in
ptp_vclock_in_use() to prevent recursive locking.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ata: pata_via: Force PIO for ATAPI devices on VT6415/VT6330
The controller has a hardware bug that can hard hang the system when
doing ATAPI DMAs without any trace of what happened. Depending on the
device attached, it can also prevent the system from booting.
In this case, the system hangs when reading the ATIP from optical media
with cdrecord -vvv -atip on an _NEC DVD_RW ND-4571A 1-01 and an
Optiarc DVD RW AD-7200A 1.06 attached to an ASRock 990FX Extreme 4,
running at UDMA/33.
The issue can be reproduced by running the same command with a cygwin
build of cdrecord on WinXP, although it requires more attempts to cause
it. The hang in that case is also resolved by forcing PIO. It doesn't
appear that VIA has produced any drivers for that OS, thus no known
workaround exists.
HDDs attached to the controller do not suffer from any DMA issues.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: sch_sfq: fix a potential crash on gso_skb handling
SFQ has an assumption of always being able to queue at least one packet.
However, after the blamed commit, sch->q.len can be inflated by packets
in sch->gso_skb, and an enqueue() on an empty SFQ qdisc can be followed
by an immediate drop.
Fix sfq_drop() to properly clear q->tail in this situation.

CVE-2025-38393 (GCVE-0-2025-38393)

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSv4/pNFS: Fix a race to wake on NFS_LAYOUT_DRAIN
We found a few different systems hung up in writeback waiting on the same
page lock, and one task waiting on the NFS_LAYOUT_DRAIN bit in
pnfs_update_layout(), however the pnfs_layout_hdr's plh_outstanding count
was zero.
It seems most likely that this is another race between the waiter and waker
similar to commit ed0172af5d6f ("SUNRPC: Fix a race to wake a sync task").
Fix it up by applying the advised barrier.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: carl9170: do not ping device which has failed to load firmware
Syzkaller reports [1, 2] crashes caused by an attempts to ping
the device which has failed to load firmware. Since such a device
doesn't pass 'ieee80211_register_hw()', an internal workqueue
managed by 'ieee80211_queue_work()' is not yet created and an
attempt to queue work on it causes null-ptr-deref.

Summary
In the Linux kernel, the following vulnerability has been resolved:
comedi: Fail COMEDI_INSNLIST ioctl if n_insns is too large
The handling of the `COMEDI_INSNLIST` ioctl allocates a kernel buffer to
hold the array of `struct comedi_insn`, getting the length from the
`n_insns` member of the `struct comedi_insnlist` supplied by the user.
The allocation will fail with a WARNING and a stack dump if it is too
large.
Avoid that by failing with an `-EINVAL` error if the supplied `n_insns`
value is unreasonable.
Define the limit on the `n_insns` value in the `MAX_INSNS` macro. Set
this to the same value as `MAX_SAMPLES` (65536), which is the maximum
allowed sum of the values of the member `n` in the array of `struct
comedi_insn`, and sensible comedi instructions will have an `n` of at
least 1.

CVE-2025-38062 (GCVE-0-2025-38062)
Vulnerability from cvelistv5 – Published: 2025-06-18 09:33 – Updated: 2025-11-03 17:33

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
genirq/msi: Store the IOMMU IOVA directly in msi_desc instead of iommu_cookie
The IOMMU translation for MSI message addresses has been a 2-step process,
separated in time:
1) iommu_dma_prepare_msi(): A cookie pointer containing the IOVA address
is stored in the MSI descriptor when an MSI interrupt is allocated.
2) iommu_dma_compose_msi_msg(): this cookie pointer is used to compute a
translated message address.
This has an inherent lifetime problem for the pointer stored in the cookie
that must remain valid between the two steps. However, there is no locking
at the irq layer that helps protect the lifetime. Today, this works under
the assumption that the iommu domain is not changed while MSI interrupts
being programmed. This is true for normal DMA API users within the kernel,
as the iommu domain is attached before the driver is probed and cannot be
changed while a driver is attached.
Classic VFIO type1 also prevented changing the iommu domain while VFIO was
running as it does not support changing the "container" after starting up.
However, iommufd has improved this so that the iommu domain can be changed
during VFIO operation. This potentially allows userspace to directly race
VFIO_DEVICE_ATTACH_IOMMUFD_PT (which calls iommu_attach_group()) and
VFIO_DEVICE_SET_IRQS (which calls into iommu_dma_compose_msi_msg()).
This potentially causes both the cookie pointer and the unlocked call to
iommu_get_domain_for_dev() on the MSI translation path to become UAFs.
Fix the MSI cookie UAF by removing the cookie pointer. The translated IOVA
address is already known during iommu_dma_prepare_msi() and cannot change.
Thus, it can simply be stored as an integer in the MSI descriptor.
The other UAF related to iommu_get_domain_for_dev() will be addressed in
patch "iommu: Make iommu_dma_prepare_msi() into a generic operation" by
using the IOMMU group mutex.

However, there is no locking\nat the irq layer that helps protect the lifetime. Today, this works under\nthe assumption that the iommu domain is not changed while MSI interrupts\nbeing programmed. This is true for normal DMA API users within the kernel,\nas the iommu domain is attached before the driver is probed and cannot be\nchanged while a driver is attached.\n\nClassic VFIO type1 also prevented changing the iommu domain while VFIO was\nrunning as it does not support changing the \"container\" after starting up.\n\nHowever, iommufd has improved this so that the iommu domain can be changed\nduring VFIO operation. This potentially allows userspace to directly race\nVFIO_DEVICE_ATTACH_IOMMUFD_PT (which calls iommu_attach_group()) and\nVFIO_DEVICE_SET_IRQS (which calls into iommu_dma_compose_msi_msg()).\n\nThis potentially causes both the cookie pointer and the unlocked call to\niommu_get_domain_for_dev() on the MSI translation path to become UAFs.\n\nFix the MSI cookie UAF by removing the cookie pointer. The translated IOVA\naddress is already known during iommu_dma_prepare_msi() and cannot change.\nThus, it can simply be stored as an integer in the MSI descriptor.\n\nThe other UAF related to iommu_get_domain_for_dev() will be addressed in\npatch \"iommu: Make iommu_dma_prepare_msi() into a generic operation\" by\nusing the IOMMU group mutex."

Summary
In the Linux kernel, the following vulnerability has been resolved:
jffs2: check jffs2_prealloc_raw_node_refs() result in few other places
Fuzzing hit another invalid pointer dereference due to the lack of
checking whether jffs2_prealloc_raw_node_refs() completed successfully.
Subsequent logic implies that the node refs have been allocated.
Handle that. The code is ready for propagating the error upwards.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: clean up FDB, MDB, VLAN entries on unbind
As explained in many places such as commit b117e1e8a86d ("net: dsa:
delete dsa_legacy_fdb_add and dsa_legacy_fdb_del"), DSA is written given
the assumption that higher layers have balanced additions/deletions.
As such, it only makes sense to be extremely vocal when those
assumptions are violated and the driver unbinds with entries still
present.
But Ido Schimmel points out a very simple situation where that is wrong:
https://lore.kernel.org/netdev/ZDazSM5UsPPjQuKr@shredder/
(also briefly discussed by me in the aforementioned commit).
Basically, while the bridge bypass operations are not something that DSA
explicitly documents, and for the majority of DSA drivers this API
simply causes them to go to promiscuous mode, that isn't the case for
all drivers. Some have the necessary requirements for bridge bypass
operations to do something useful - see dsa_switch_supports_uc_filtering().
Although in tools/testing/selftests/net/forwarding/local_termination.sh,
we made an effort to popularize better mechanisms to manage address
filters on DSA interfaces from user space - namely macvlan for unicast,
and setsockopt(IP_ADD_MEMBERSHIP) - through mtools - for multicast, the
fact is that 'bridge fdb add ... self static local' also exists as
kernel UAPI, and might be useful to someone, even if only for a quick
hack.
It seems counter-productive to block that path by implementing shim
.ndo_fdb_add and .ndo_fdb_del operations which just return -EOPNOTSUPP
in order to prevent the ndo_dflt_fdb_add() and ndo_dflt_fdb_del() from
running, although we could do that.
Accepting that cleanup is necessary seems to be the only option.
Especially since we appear to be coming back at this from a different
angle as well. Russell King is noticing that the WARN_ON() triggers even
for VLANs:
https://lore.kernel.org/netdev/Z_li8Bj8bD4-BYKQ@shell.armlinux.org.uk/
What happens in the bug report above is that dsa_port_do_vlan_del() fails,
then the VLAN entry lingers on, and then we warn on unbind and leak it.
This is not a straight revert of the blamed commit, but we now add an
informational print to the kernel log (to still have a way to see
that bugs exist), and some extra comments gathered from past years'
experience, to justify the logic.

Summary
In the Linux kernel, the following vulnerability has been resolved:
jffs2: check that raw node were preallocated before writing summary
Syzkaller detected a kernel bug in jffs2_link_node_ref, caused by fault
injection in jffs2_prealloc_raw_node_refs. jffs2_sum_write_sumnode doesn't
check return value of jffs2_prealloc_raw_node_refs and simply lets any
error propagate into jffs2_sum_write_data, which eventually calls
jffs2_link_node_ref in order to link the summary to an expectedly allocated
node.

CVE-2025-38275 (GCVE-0-2025-38275)

Summary
In the Linux kernel, the following vulnerability has been resolved:
phy: qcom-qmp-usb: Fix an NULL vs IS_ERR() bug
The qmp_usb_iomap() helper function currently returns the raw result of
devm_ioremap() for non-exclusive mappings. Since devm_ioremap() may return
a NULL pointer and the caller only checks error pointers with IS_ERR(),
NULL could bypass the check and lead to an invalid dereference.
Fix the issue by checking if devm_ioremap() returns NULL. When it does,
qmp_usb_iomap() now returns an error pointer via IOMEM_ERR_PTR(-ENOMEM),
ensuring safe and consistent error handling.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm: Fix another leak in the submit error path
put_unused_fd() doesn't free the installed file, if we've already done
fd_install(). So we need to also free the sync_file.

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
media: imx-jpeg: Cleanup after an allocation error
When allocation failures are not cleaned up by the driver, further
allocation errors will be false-positives, which will cause buffers to
remain uninitialized and cause NULL pointer dereferences.
Ensure proper cleanup of failed allocations to prevent these issues.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: smartpqi: Fix smp_processor_id() call trace for preemptible kernels
Correct kernel call trace when calling smp_processor_id() when called in
preemptible kernels by using raw_smp_processor_id().
smp_processor_id() checks to see if preemption is disabled and if not,
issue an error message followed by a call to dump_stack().
Brief example of call trace:
kernel: check_preemption_disabled: 436 callbacks suppressed
kernel: BUG: using smp_processor_id() in preemptible [00000000]
code: kworker/u1025:0/2354

Summary
In the Linux kernel, the following vulnerability has been resolved:
jbd2: fix data-race and null-ptr-deref in jbd2_journal_dirty_metadata()
Since handle->h_transaction may be a NULL pointer, so we should change it
to call is_handle_aborted(handle) first before dereferencing it.
And the following data-race was reported in my fuzzer:
==================================================================
BUG: KCSAN: data-race in jbd2_journal_dirty_metadata / jbd2_journal_dirty_metadata

....
value changed: 0x00000000 -> 0x00000001
==================================================================
This issue is caused by missing data-race annotation for jh->b_modified.
Therefore, the missing annotation needs to be added.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix invalid access to memory
In ath12k_dp_rx_msdu_coalesce(), rxcb is fetched from skb and boolean
is_continuation is part of rxcb.
Currently, after freeing the skb, the rxcb->is_continuation accessed
again which is wrong since the memory is already freed.
This might lead use-after-free error.
Hence, fix by locally defining bool is_continuation from rxcb,
so that after freeing skb, is_continuation can be used.
Compile tested only.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
rpl: Fix use-after-free in rpl_do_srh_inline().
Running lwt_dst_cache_ref_loop.sh in selftest with KASAN triggers
the splat below [0].
rpl_do_srh_inline() fetches ipv6_hdr(skb) and accesses it after
skb_cow_head(), which is illegal as the header could be freed then.
Let's fix it by making oldhdr to a local struct instead of a pointer.
[0]:
[root@fedora net]# ./lwt_dst_cache_ref_loop.sh
...
TEST: rpl (input)

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/hugetlb: fix huge_pmd_unshare() vs GUP-fast race
huge_pmd_unshare() drops a reference on a page table that may have
previously been shared across processes, potentially turning it into a
normal page table used in another process in which unrelated VMAs can
afterwards be installed.
If this happens in the middle of a concurrent gup_fast(), gup_fast() could
end up walking the page tables of another process. While I don't see any
way in which that immediately leads to kernel memory corruption, it is
really weird and unexpected.
Fix it with an explicit broadcast IPI through tlb_remove_table_sync_one(),
just like we do in khugepaged when removing page tables for a THP
collapse.
Severity ?

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_set_pipapo_avx2: fix initial map fill
If the first field doesn't cover the entire start map, then we must zero
out the remainder, else we leak those bits into the next match round map.
The early fix was incomplete and did only fix up the generic C
implementation.
A followup patch adds a test case to nft_concat_range.sh.
Severity ?
No CVSS data available.

CVE-2025-38277 (GCVE-0-2025-38277)
Vulnerability from cvelistv5 – Published: 2025-07-10 07:41 – Updated: 2025-11-03 17:36

Summary
In the Linux kernel, the following vulnerability has been resolved:
mtd: nand: ecc-mxic: Fix use of uninitialized variable ret
If ctx->steps is zero, the loop processing ECC steps is skipped,
and the variable ret remains uninitialized. It is later checked
and returned, which leads to undefined behavior and may cause
unpredictable results in user space or kernel crashes.
This scenario can be triggered in edge cases such as misconfigured
geometry, ECC engine misuse, or if ctx->steps is not validated
after initialization.
Initialize ret to zero before the loop to ensure correct and safe
behavior regardless of the ctx->steps value.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

CVE-2025-38034 (GCVE-0-2025-38034)
Vulnerability from cvelistv5 – Published: 2025-06-18 09:33 – Updated: 2025-11-03 17:33

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: correct the order of prelim_ref arguments in btrfs__prelim_ref
btrfs_prelim_ref() calls the old and new reference variables in the
incorrect order. This causes a NULL pointer dereference because oldref
is passed as NULL to trace_btrfs_prelim_ref_insert().
Note, trace_btrfs_prelim_ref_insert() is being called with newref as
oldref (and oldref as NULL) on purpose in order to print out
the values of newref.
To reproduce:
echo 1 > /sys/kernel/debug/tracing/events/btrfs/btrfs_prelim_ref_insert/enable
Perform some writeback operations.
Backtrace:

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: wcd9335: Fix missing free of regulator supplies
Driver gets and enables all regulator supplies in probe path
(wcd9335_parse_dt() and wcd9335_power_on_reset()), but does not cleanup
in final error paths and in unbind (missing remove() callback). This
leads to leaked memory and unbalanced regulator enable count during
probe errors or unbind.
Fix this by converting entire code into devm_regulator_bulk_get_enable()
which also greatly simplifies the code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (ftsteutates) Fix TOCTOU race in fts_read()
In the fts_read() function, when handling hwmon_pwm_auto_channels_temp,
the code accesses the shared variable data->fan_source[channel] twice
without holding any locks. It is first checked against
FTS_FAN_SOURCE_INVALID, and if the check passes, it is read again
when used as an argument to the BIT() macro.
This creates a Time-of-Check to Time-of-Use (TOCTOU) race condition.
Another thread executing fts_update_device() can modify the value of
data->fan_source[channel] between the check and its use. If the value
is changed to FTS_FAN_SOURCE_INVALID (0xff) during this window, the
BIT() macro will be called with a large shift value (BIT(255)).
A bit shift by a value greater than or equal to the type width is
undefined behavior and can lead to a crash or incorrect values being
returned to userspace.
Fix this by reading data->fan_source[channel] into a local variable
once, eliminating the race condition. Additionally, add a bounds check
to ensure the value is less than BITS_PER_LONG before passing it to
the BIT() macro, making the code more robust against undefined behavior.
This possible bug was found by an experimental static analysis tool
developed by our team.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: Correct signedness in skb remaining space calculation
Syzkaller reported a bug [1] where sk->sk_forward_alloc can overflow.
When we send data, if an skb exists at the tail of the write queue, the
kernel will attempt to append the new data to that skb. However, the code
that checks for available space in the skb is flawed:
'''
copy = size_goal - skb->len
'''
The types of the variables involved are:
'''
copy: ssize_t (s64 on 64-bit systems)
size_goal: int
skb->len: unsigned int
'''
Due to C's type promotion rules, the signed size_goal is converted to an
unsigned int to match skb->len before the subtraction. The result is an
unsigned int.
When this unsigned int result is then assigned to the s64 copy variable,
it is zero-extended, preserving its non-negative value. Consequently, copy
is always >= 0.
Assume we are sending 2GB of data and size_goal has been adjusted to a
value smaller than skb->len. The subtraction will result in copy holding a
very large positive integer. In the subsequent logic, this large value is
used to update sk->sk_forward_alloc, which can easily cause it to overflow.
The syzkaller reproducer uses TCP_REPAIR to reliably create this
condition. However, this can also occur in real-world scenarios. The
tcp_bound_to_half_wnd() function can also reduce size_goal to a small
value. This would cause the subsequent tcp_wmem_schedule() to set
sk->sk_forward_alloc to a value close to INT_MAX. Further memory
allocation requests would then cause sk_forward_alloc to wrap around and
become negative.

Summary
In the Linux kernel, the following vulnerability has been resolved:
efi: Don't map the entire mokvar table to determine its size
Currently, when validating the mokvar table, we (re)map the entire table
on each iteration of the loop, adding space as we discover new entries.
If the table grows over a certain size, this fails due to limitations of
early_memmap(), and we get a failure and traceback:
------------[ cut here ]------------

mokvar: Failed to map EFI MOKvar config table pa=0x7c4c3000, size=265187.
Mapping the entire structure isn't actually necessary, as we don't ever
need more than one entry header mapped at once.
Changes efi_mokvar_table_init() to only map each entry header, not the
entire table, when determining the table size. Since we're not mapping
any data past the variable name, it also changes the code to enforce
that each variable name is NUL terminated, rather than attempting to
verify it in place.

ALSA: usb-audio: Kill timer properly at removal
The USB-audio MIDI code initializes the timer, but in a rare case, the
driver might be freed without the disconnect call. This leaves the
timer in an active state while the assigned object is released via
snd_usbmidi_free(), which ends up with a kernel warning when the debug
configuration is enabled, as spotted by fuzzer.
For avoiding the problem, put timer_shutdown_sync() at
snd_usbmidi_free(), so that the timer can be killed properly.
While we're at it, replace the existing timer_delete_sync() at the
disconnect callback with timer_shutdown_sync(), too.

CVE-2025-38094 (GCVE-0-2025-38094)
Vulnerability from cvelistv5 – Published: 2025-07-03 07:44 – Updated: 2025-11-03 19:58

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: cadence: macb: Fix a possible deadlock in macb_halt_tx.
There is a situation where after THALT is set high, TGO stays high as
well. Because jiffies are never updated, as we are in a context with
interrupts disabled, we never exit that loop and have a deadlock.
That deadlock was noticed on a sama5d4 device that stayed locked for days.
Use retries instead of jiffies so that the timeout really works and we do
not have a deadlock anymore.
Severity ?
No CVSS data available.

Kernel panic - not syncing: Fatal exception
[ Analysis ]
We believe that we have found a concurrency bug in the `fs/jfs` module
that results in a null pointer dereference. There is a closely related
issue which has been fixed:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d6c1b3599b2feb5c7291f5ac3a36e5fa7cedb234
... but, unfortunately, the accepted patch appears to still be
susceptible to a null pointer dereference under some interleavings.
To trigger the bug, we think that `JFS_SBI(ipbmap->i_sb)->bmap` is set
to NULL in `dbFreeBits` and then dereferenced in `jfs_ioc_trim`. This
bug manifests quite rarely under normal circumstances, but is
triggereable from a syz-program.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix a race between renames and directory logging
We have a race between a rename and directory inode logging that if it
happens and we crash/power fail before the rename completes, the next time
the filesystem is mounted, the log replay code will end up deleting the
file that was being renamed.
This is best explained following a step by step analysis of an interleaving
of steps that lead into this situation.
Consider the initial conditions:
1) We are at transaction N;
2) We have directories A and B created in a past transaction (< N);
3) We have inode X corresponding to a file that has 2 hardlinks, one in
directory A and the other in directory B, so we'll name them as
"A/foo_link1" and "B/foo_link2". Both hard links were persisted in a
past transaction (< N);
4) We have inode Y corresponding to a file that as a single hard link and
is located in directory A, we'll name it as "A/bar". This file was also
persisted in a past transaction (< N).
The steps leading to a file loss are the following and for all of them we
are under transaction N:
1) Link "A/foo_link1" is removed, so inode's X last_unlink_trans field
is updated to N, through btrfs_unlink() -> btrfs_record_unlink_dir();
2) Task A starts a rename for inode Y, with the goal of renaming from
"A/bar" to "A/baz", so we enter btrfs_rename();
3) Task A inserts the new BTRFS_INODE_REF_KEY for inode Y by calling
btrfs_insert_inode_ref();
4) Because the rename happens in the same directory, we don't set the
last_unlink_trans field of directoty A's inode to the current
transaction id, that is, we don't cal btrfs_record_unlink_dir();
5) Task A then removes the entries from directory A (BTRFS_DIR_ITEM_KEY
and BTRFS_DIR_INDEX_KEY items) when calling __btrfs_unlink_inode()
(actually the dir index item is added as a delayed item, but the
effect is the same);
6) Now before task A adds the new entry "A/baz" to directory A by
calling btrfs_add_link(), another task, task B is logging inode X;
7) Task B starts a fsync of inode X and after logging inode X, at
btrfs_log_inode_parent() it calls btrfs_log_all_parents(), since
inode X has a last_unlink_trans value of N, set at in step 1;
8) At btrfs_log_all_parents() we search for all parent directories of
inode X using the commit root, so we find directories A and B and log
them. Bu when logging direct A, we don't have a dir index item for
inode Y anymore, neither the old name "A/bar" nor for the new name
"A/baz" since the rename has deleted the old name but has not yet
inserted the new name - task A hasn't called yet btrfs_add_link() to
do that.
Note that logging directory A doesn't fallback to a transaction
commit because its last_unlink_trans has a lower value than the
current transaction's id (see step 4);
9) Task B finishes logging directories A and B and gets back to
btrfs_sync_file() where it calls btrfs_sync_log() to persist the log
tree;
10) Task B successfully persisted the log tree, btrfs_sync_log() completed
with success, and a power failure happened.
We have a log tree without any directory entry for inode Y, so the
log replay code deletes the entry for inode Y, name "A/bar", from the
subvolume tree since it doesn't exist in the log tree and the log
tree is authorative for its index (we logged a BTRFS_DIR_LOG_INDEX_KEY
item that covers the index range for the dentry that corresponds to
"A/bar").
Since there's no other hard link for inode Y and the log replay code
deletes the name "A/bar", the file is lost.
The issue wouldn't happen if task B synced the log only after task A
called btrfs_log_new_name(), which would update the log with the new name
for inode Y ("A/bar").
Fix this by pinning the log root during renames before removing the old
directory entry, and unpinning af

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: Fix buffer overflow when parsing NFS reparse points
ReparseDataLength is sum of the InodeType size and DataBuffer size.
So to get DataBuffer size it is needed to subtract InodeType's size from
ReparseDataLength.
Function cifs_strndup_from_utf16() is currentlly accessing buf->DataBuffer
at position after the end of the buffer because it does not subtract
InodeType size from the length. Fix this problem and correctly subtract
variable len.
Member InodeType is present only when reparse buffer is large enough. Check
for ReparseDataLength before accessing InodeType to prevent another invalid
memory access.
Major and minor rdev values are present also only when reparse buffer is
large enough. Check for reparse buffer size before calling reparse_mkdev().
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/cma: Fix hang when cma_netevent_callback fails to queue_work
The cited commit fixed a crash when cma_netevent_callback was called for
a cma_id while work on that id from a previous call had not yet started.
The work item was re-initialized in the second call, which corrupted the
work item currently in the work queue.
However, it left a problem when queue_work fails (because the item is
still pending in the work queue from a previous call). In this case,
cma_id_put (which is called in the work handler) is therefore not
called. This results in a userspace process hang (zombie process).
Fix this by calling cma_id_put() if queue_work fails.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau: fix a use-after-free in r535_gsp_rpc_push()
The RPC container is released after being passed to r535_gsp_rpc_send().
When sending the initial fragment of a large RPC and passing the
caller's RPC container, the container will be freed prematurely. Subsequent
attempts to send remaining fragments will therefore result in a
use-after-free.
Allocate a temporary RPC container for holding the initial fragment of a
large RPC when sending. Free the caller's container when all fragments
are successfully sent.

Summary
In the Linux kernel, the following vulnerability has been resolved:
configfs-tsm-report: Fix NULL dereference of tsm_ops
Unlike sysfs, the lifetime of configfs objects is controlled by
userspace. There is no mechanism for the kernel to find and delete all
created config-items. Instead, the configfs-tsm-report mechanism has an
expectation that tsm_unregister() can happen at any time and cause
established config-item access to start failing.
That expectation is not fully satisfied. While tsm_report_read(),
tsm_report_{is,is_bin}_visible(), and tsm_report_make_item() safely fail
if tsm_ops have been unregistered, tsm_report_privlevel_store()
tsm_report_provider_show() fail to check for ops registration. Add the
missing checks for tsm_ops having been removed.
Now, in supporting the ability for tsm_unregister() to always succeed,
it leaves the problem of what to do with lingering config-items. The
expectation is that the admin that arranges for the ->remove() (unbind)
of the ${tsm_arch}-guest driver is also responsible for deletion of all
open config-items. Until that deletion happens, ->probe() (reload /
bind) of the ${tsm_arch}-guest driver fails.
This allows for emergency shutdown / revocation of attestation
interfaces, and requires coordinated restart.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/iwcm: Fix use-after-free of work objects after cm_id destruction
The commit 59c68ac31e15 ("iw_cm: free cm_id resources on the last
deref") simplified cm_id resource management by freeing cm_id once all
references to the cm_id were removed. The references are removed either
upon completion of iw_cm event handlers or when the application destroys
the cm_id. This commit introduced the use-after-free condition where
cm_id_private object could still be in use by event handler works during
the destruction of cm_id. The commit aee2424246f9 ("RDMA/iwcm: Fix a
use-after-free related to destroying CM IDs") addressed this use-after-
free by flushing all pending works at the cm_id destruction.
However, still another use-after-free possibility remained. It happens
with the work objects allocated for each cm_id_priv within
alloc_work_entries() during cm_id creation, and subsequently freed in
dealloc_work_entries() once all references to the cm_id are removed.
If the cm_id's last reference is decremented in the event handler work,
the work object for the work itself gets removed, and causes the use-
after-free BUG below:

the last reference to the cm_id is decremented not in the event handler
works, but in the cm_id destruction context. For that purpose, mo

The references are removed either\nupon completion of iw_cm event handlers or when the application destroys\nthe cm_id. This commit introduced the use-after-free condition where\ncm_id_private object could still be in use by event handler works during\nthe destruction of cm_id. The commit aee2424246f9 (\"RDMA/iwcm: Fix a\nuse-after-free related to destroying CM IDs\") addressed this use-after-\nfree by flushing all pending works at the cm_id destruction.\n\nHowever, still another use-after-free possibility remained. It happens\nwith the work objects allocated for each cm_id_priv within\nalloc_work_entries() during cm_id creation, and subsequently freed in\ndealloc_work_entries() once all references to the cm_id are removed.\nIf the cm_id\u0027s last reference is decremented in the event handler work,\nthe work object for the work itself gets removed, and causes the use-\nafter-free BUG below:\n\n BUG: KASAN: slab-use-after-free in __pwq_activate_work+0x1ff/0x250\n Read of size 8 at addr ffff88811f9cf800 by task kworker/u16:1/147091\n\n CPU: 2 UID: 0 PID: 147091 Comm: kworker/u16:1 Not tainted 6.15.0-rc2+ #27 PREEMPT(voluntary)\n Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-3.fc41 04/01/2014\n Workqueue: 0x0 (iw_cm_wq)\n Call Trace:\n \u003cTASK\u003e\n dump_stack_lvl+0x6a/0x90\n print_report+0x174/0x554\n ? __virt_addr_valid+0x208/0x430\n ? __pwq_activate_work+0x1ff/0x250\n kasan_report+0xae/0x170\n ? __pwq_activate_work+0x1ff/0x250\n __pwq_activate_work+0x1ff/0x250\n pwq_dec_nr_in_flight+0x8c5/0xfb0\n process_one_work+0xc11/0x1460\n ? __pfx_process_one_work+0x10/0x10\n ? assign_work+0x16c/0x240\n worker_thread+0x5ef/0xfd0\n ? __pfx_worker_thread+0x10/0x10\n kthread+0x3b0/0x770\n ? __pfx_kthread+0x10/0x10\n ? rcu_is_watching+0x11/0xb0\n ? _raw_spin_unlock_irq+0x24/0x50\n ? rcu_is_watching+0x11/0xb0\n ? __pfx_kthread+0x10/0x10\n ret_from_fork+0x30/0x70\n ? __pfx_kthread+0x10/0x10\n ret_from_fork_asm+0x1a/0x30\n \u003c/TASK\u003e\n\n Allocated by task 147416:\n kasan_save_stack+0x2c/0x50\n kasan_save_track+0x10/0x30\n __kasan_kmalloc+0xa6/0xb0\n alloc_work_entries+0xa9/0x260 [iw_cm]\n iw_cm_connect+0x23/0x4a0 [iw_cm]\n rdma_connect_locked+0xbfd/0x1920 [rdma_cm]\n nvme_rdma_cm_handler+0x8e5/0x1b60 [nvme_rdma]\n cma_cm_event_handler+0xae/0x320 [rdma_cm]\n cma_work_handler+0x106/0x1b0 [rdma_cm]\n process_one_work+0x84f/0x1460\n worker_thread+0x5ef/0xfd0\n kthread+0x3b0/0x770\n ret_from_fork+0x30/0x70\n ret_from_fork_asm+0x1a/0x30\n\n Freed by task 147091:\n kasan_save_stack+0x2c/0x50\n kasan_save_track+0x10/0x30\n kasan_save_free_info+0x37/0x60\n __kasan_slab_free+0x4b/0x70\n kfree+0x13a/0x4b0\n dealloc_work_entries+0x125/0x1f0 [iw_cm]\n iwcm_deref_id+0x6f/0xa0 [iw_cm]\n cm_work_handler+0x136/0x1ba0 [iw_cm]\n process_one_work+0x84f/0x1460\n worker_thread+0x5ef/0xfd0\n kthread+0x3b0/0x770\n ret_from_fork+0x30/0x70\n ret_from_fork_asm+0x1a/0x30\n\n Last potentially related work creation:\n kasan_save_stack+0x2c/0x50\n kasan_record_aux_stack+0xa3/0xb0\n __queue_work+0x2ff/0x1390\n queue_work_on+0x67/0xc0\n cm_event_handler+0x46a/0x820 [iw_cm]\n siw_cm_upcall+0x330/0x650 [siw]\n siw_cm_work_handler+0x6b9/0x2b20 [siw]\n process_one_work+0x84f/0x1460\n worker_thread+0x5ef/0xfd0\n kthread+0x3b0/0x770\n ret_from_fork+0x30/0x70\n ret_from_fork_asm+0x1a/0x30\n\nThis BUG is reproducible by repeating the blktests test case nvme/061\nfor the rdma transport and the siw driver.\n\nTo avoid the use-after-free of cm_id_private work objects, ensure that\nthe last reference to the cm_id is decremented not in the event handler\nworks, but in the cm_id destruction context.

Summary
In the Linux kernel, the following vulnerability has been resolved:
IB/cm: Drop lockdep assert and WARN when freeing old msg
The send completion handler can run after cm_id has advanced to another
message. The cm_id lock is not needed in this case, but a recent change
re-used cm_free_priv_msg(), which asserts that the lock is held and
WARNs if the cm_id's currently outstanding msg is different than the one
being freed.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sch_hfsc: make hfsc_qlen_notify() idempotent
hfsc_qlen_notify() is not idempotent either and not friendly
to its callers, like fq_codel_dequeue(). Let's make it idempotent
to ease qdisc_tree_reduce_backlog() callers' life:
1. update_vf() decreases cl->cl_nactive, so we can check whether it is
non-zero before calling it.
2. eltree_remove() always removes RB node cl->el_node, but we can use
RB_EMPTY_NODE() + RB_CLEAR_NODE() to make it safe.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sockmap, vsock: For connectible sockets allow only connected
sockmap expects all vsocks to have a transport assigned, which is expressed
in vsock_proto::psock_update_sk_prot(). However, there is an edge case
where an unconnected (connectible) socket may lose its previously assigned
transport. This is handled with a NULL check in the vsock/BPF recv path.
Another design detail is that listening vsocks are not supposed to have any
transport assigned at all. Which implies they are not supported by the
sockmap. But this is complicated by the fact that a socket, before
switching to TCP_LISTEN, may have had some transport assigned during a
failed connect() attempt. Hence, we may end up with a listening vsock in a
sockmap, which blows up quickly:
KASAN: null-ptr-deref in range [0x0000000000000120-0x0000000000000127]

For connectible sockets, instead of relying solely on the state of
vsk->transport, tell sockmap to only allow those representing established
connections. This aligns with the behaviour for AF_INET and AF_UNIX.

Summary
In the Linux kernel, the following vulnerability has been resolved:
calipso: Fix null-ptr-deref in calipso_req_{set,del}attr().
syzkaller reported a null-ptr-deref in sock_omalloc() while allocating
a CALIPSO option. [0]
The NULL is of struct sock, which was fetched by sk_to_full_sk() in
calipso_req_setattr().
Since commit a1a5344ddbe8 ("tcp: avoid two atomic ops for syncookies"),
reqsk->rsk_listener could be NULL when SYN Cookie is returned to its
client, as hinted by the leading SYN Cookie log.
Here are 3 options to fix the bug:
1) Return 0 in calipso_req_setattr()
2) Return an error in calipso_req_setattr()
3) Alaways set rsk_listener
1) is no go as it bypasses LSM, but 2) effectively disables SYN Cookie
for CALIPSO. 3) is also no go as there have been many efforts to reduce
atomic ops and make TCP robust against DDoS. See also commit 3b24d854cb35
("tcp/dccp: do not touch listener sk_refcnt under synflood").
As of the blamed commit, SYN Cookie already did not need refcounting,
and no one has stumbled on the bug for 9 years, so no CALIPSO user will
care about SYN Cookie.
Let's return an error in calipso_req_setattr() and calipso_req_delattr()
in the SYN Cookie case.
This can be reproduced by [1] on Fedora and now connect() of nc times out.

[0]\n\nThe NULL is of struct sock, which was fetched by sk_to_full_sk() in\ncalipso_req_setattr().\n\nSince commit a1a5344ddbe8 (\"tcp: avoid two atomic ops for syncookies\"),\nreqsk-\u003ersk_listener could be NULL when SYN Cookie is returned to its\nclient, as hinted by the leading SYN Cookie log.\n\nHere are 3 options to fix the bug:\n\n 1) Return 0 in calipso_req_setattr()\n 2) Return an error in calipso_req_setattr()\n 3) Alaways set rsk_listener\n\n1) is no go as it bypasses LSM, but 2) effectively disables SYN Cookie\nfor CALIPSO. 3) is also no go as there have been many efforts to reduce\natomic ops and make TCP robust against DDoS. See also commit 3b24d854cb35\n(\"tcp/dccp: do not touch listener sk_refcnt under synflood\").\n\nAs of the blamed commit, SYN Cookie already did not need refcounting,\nand no one has stumbled on the bug for 9 years, so no CALIPSO user will\ncare about SYN Cookie.\n\nLet\u0027s return an error in calipso_req_setattr() and calipso_req_delattr()\nin the SYN Cookie case.\n\nThis can be reproduced by [1] on Fedora and now connect() of nc times out.\n\n[0]:\nTCP: request_sock_TCPv6: Possible SYN flooding on port [::]:20002.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPICA: fix acpi parse and parseext cache leaks
ACPICA commit 8829e70e1360c81e7a5a901b5d4f48330e021ea5
I'm Seunghun Han, and I work for National Security Research Institute of
South Korea.
I have been doing a research on ACPI and found an ACPI cache leak in ACPI
early abort cases.
Boot log of ACPI cache leak is as follows:

I analyzed this memory leak in detail. I found that “Acpi-State” cache and
“Acpi-Parse” cache were merged because the size of cache objects was same
slab cache size.
I finally found “Acpi-Parse” cache and “Acpi-parse_ext” cache were leaked
using SLAB_NEVER_MERGE flag in kmem_cache_create() function.
Real ACPI cache leak point is as follows:

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: ecdsa - Harden against integer overflows in DIV_ROUND_UP()
Herbert notes that DIV_ROUND_UP() may overflow unnecessarily if an ecdsa
implementation's ->key_size() callback returns an unusually large value.
Herbert instead suggests (for a division by 8):
X / 8 + !!(X & 7)
Based on this formula, introduce a generic DIV_ROUND_UP_POW2() macro and
use it in lieu of DIV_ROUND_UP() for ->key_size() return values.
Additionally, use the macro in ecc_digits_from_bytes(), whose "nbytes"
parameter is a ->key_size() return value in some instances, or a
user-specified ASN.1 length in the case of ecdsa_get_signature_rs().

CVE-2025-38362 (GCVE-0-2025-38362)
Vulnerability from cvelistv5 – Published: 2025-07-25 12:47 – Updated: 2025-11-03 17:37

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null pointer check for get_first_active_display()
The function mod_hdcp_hdcp1_enable_encryption() calls the function
get_first_active_display(), but does not check its return value.
The return value is a null pointer if the display list is empty.
This will lead to a null pointer dereference in
mod_hdcp_hdcp2_enable_encryption().
Add a null pointer check for get_first_active_display() and return
MOD_HDCP_STATUS_DISPLAY_NOT_FOUND if the function return null.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
perf: Fix sample vs do_exit()
Baisheng Gao reported an ARM64 crash, which Mark decoded as being a
synchronous external abort -- most likely due to trying to access
MMIO in bad ways.
The crash further shows perf trying to do a user stack sample while in
exit_mmap()'s tlb_finish_mmu() -- i.e. while tearing down the address
space it is trying to access.
It turns out that we stop perf after we tear down the userspace mm; a
receipie for disaster, since perf likes to access userspace for
various reasons.
Flip this order by moving up where we stop perf in do_exit().
Additionally, harden PERF_SAMPLE_CALLCHAIN and PERF_SAMPLE_STACK_USER
to abort when the current task does not have an mm (exit_mm() makes
sure to set current->mm = NULL; before commencing with the actual
teardown). Such that CPU wide events don't trip on this same problem.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/nfs/read: fix double-unlock bug in nfs_return_empty_folio()
Sometimes, when a file was read while it was being truncated by
another NFS client, the kernel could deadlock because folio_unlock()
was called twice, and the second call would XOR back the `PG_locked`
flag.
Most of the time (depending on the timing of the truncation), nobody
notices the problem because folio_unlock() gets called three times,
which flips `PG_locked` back off:
1. vfs_read, nfs_read_folio, ... nfs_read_add_folio,
nfs_return_empty_folio
2. vfs_read, nfs_read_folio, ... netfs_read_collection,
netfs_unlock_abandoned_read_pages
3. vfs_read, ... nfs_do_read_folio, nfs_read_add_folio,
nfs_return_empty_folio
The problem is that nfs_read_add_folio() is not supposed to unlock the
folio if fscache is enabled, and a nfs_netfs_folio_unlock() check is
missing in nfs_return_empty_folio().
Rarely this leads to a warning in netfs_read_collection():

folio_wait_bit_common(), waiting for `PG_locked` to disappear, which
never happens because nobody is really holding the folio lock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Avoid using sk_socket after free when sending
The sk->sk_socket is not locked or referenced in backlog thread, and
during the call to skb_send_sock(), there is a race condition with
the release of sk_socket. All types of sockets(tcp/udp/unix/vsock)
will be affected.
Race conditions:
'''
CPU0 CPU1
backlog::skb_send_sock
sendmsg_unlocked
sock_sendmsg
sock_sendmsg_nosec
close(fd):
...
ops->release() -> sock_map_close()
sk_socket->ops = NULL
free(socket)
sock->ops->sendmsg
^
panic here
'''
The ref of psock become 0 after sock_map_close() executed.
'''
void sock_map_close()
{
...
if (likely(psock)) {
...
// !! here we remove psock and the ref of psock become 0
sock_map_remove_links(sk, psock)
psock = sk_psock_get(sk);
if (unlikely(!psock))
goto no_psock; <=== Control jumps here via goto
...
cancel_delayed_work_sync(&psock->work); <=== not executed
sk_psock_put(sk, psock);
...
}
'''
Based on the fact that we already wait for the workqueue to finish in
sock_map_close() if psock is held, we simply increase the psock
reference count to avoid race conditions.
With this patch, if the backlog thread is running, sock_map_close() will
wait for the backlog thread to complete and cancel all pending work.
If no backlog running, any pending work that hasn't started by then will
fail when invoked by sk_psock_get(), as the psock reference count have
been zeroed, and sk_psock_drop() will cancel all jobs via
cancel_delayed_work_sync().
In summary, we require synchronization to coordinate the backlog thread
and close() thread.
The panic I catched:
'''
Workqueue: events sk_psock_backlog
RIP: 0010:sock_sendmsg+0x21d/0x440
RAX: 0000000000000000 RBX: ffffc9000521fad8 RCX: 0000000000000001

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Initialize obj_event->obj_sub_list before xa_insert
The obj_event may be loaded immediately after inserted, then if the
list_head is not initialized then we may get a poisonous pointer. This
fixes the crash below:

Summary
In the Linux kernel, the following vulnerability has been resolved:
idpf: convert control queue mutex to a spinlock
With VIRTCHNL2_CAP_MACFILTER enabled, the following warning is generated
on module load:

The sequence is as follows:

dev_set_rx_mode() - > # disables BH and grabs "dev->addr_list_lock"
idpf_set_rx_mode() -> # proceed only if VIRTCHNL2_CAP_MACFILTER is ON
__dev_uc_sync() ->
idpf_add_mac_filter ->
idpf_add_del_mac_filters ->
idpf_send_mb_msg() ->
idpf_mb_clean() ->
idpf_ctlq_clean_sq() # mutex_lock(cq_lock)
Fix by converting cq_lock to a spinlock. All operations under the new
lock are safe except freeing the DMA memory, which may use vunmap(). Fix
by requesting a contiguous physical memory for the DMA mapping.

Summary
In the Linux kernel, the following vulnerability has been resolved:
rose: fix dangling neighbour pointers in rose_rt_device_down()
There are two bugs in rose_rt_device_down() that can cause
use-after-free:
1. The loop bound `t->count` is modified within the loop, which can
cause the loop to terminate early and miss some entries.
2. When removing an entry from the neighbour array, the subsequent entries
are moved up to fill the gap, but the loop index `i` is still
incremented, causing the next entry to be skipped.
For example, if a node has three neighbours (A, A, B) with count=3 and A
is being removed, the second A is not checked.
i=0: (A, A, B) -> (A, B) with count=2
^ checked
i=1: (A, B) -> (A, B) with count=2
^ checked (B, not A!)
i=2: (doesn't occur because i < count is false)
This leaves the second A in the array with count=2, but the rose_neigh
structure has been freed. Code that accesses these entries assumes that
the first `count` entries are valid pointers, causing a use-after-free
when it accesses the dangling pointer.
Fix both issues by iterating over the array in reverse order with a fixed
loop bound. This ensures that all entries are examined and that the removal
of an entry doesn't affect subsequent iterations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Check rcu_read_lock_trace_held() in bpf_map_lookup_percpu_elem()
bpf_map_lookup_percpu_elem() helper is also available for sleepable bpf
program. When BPF JIT is disabled or under 32-bit host,
bpf_map_lookup_percpu_elem() will not be inlined. Using it in a
sleepable bpf program will trigger the warning in
bpf_map_lookup_percpu_elem(), because the bpf program only holds
rcu_read_lock_trace lock. Therefore, add the missed check.
Severity ?

Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: ims-pcu - check record size in ims_pcu_flash_firmware()
The "len" variable comes from the firmware and we generally do
trust firmware, but it's always better to double check. If the "len"
is too large it could result in memory corruption when we do
"memcpy(fragment->data, rec->data, len);"
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
hisi_acc_vfio_pci: fix XQE dma address error
The dma addresses of EQE and AEQE are wrong after migration and
results in guest kernel-mode encryption services failure.
Comparing the definition of hardware registers, we found that
there was an error when the data read from the register was
combined into an address. Therefore, the address combination
sequence needs to be corrected.
Even after fixing the above problem, we still have an issue
where the Guest from an old kernel can get migrated to
new kernel and may result in wrong data.
In order to ensure that the address is correct after migration,
if an old magic number is detected, the dma address needs to be
updated.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mtk-sd: Prevent memory corruption from DMA map failure
If msdc_prepare_data() fails to map the DMA region, the request is
not prepared for data receiving, but msdc_start_data() proceeds
the DMA with previous setting.
Since this will lead a memory corruption, we have to stop the
request operation soon after the msdc_prepare_data() fails to
prepare it.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/gem: Acquire references on GEM handles for framebuffers
A GEM handle can be released while the GEM buffer object is attached
to a DRM framebuffer. This leads to the release of the dma-buf backing
the buffer object, if any. [1] Trying to use the framebuffer in further
mode-setting operations leads to a segmentation fault. Most easily
happens with driver that use shadow planes for vmap-ing the dma-buf
during a page flip. An example is shown below.

[ 157.346424] ---[ end trace 0000000000000000 ]---
Acquiring GEM handles for the framebuffer's GEM buffer objects prevents
this from happening. The framebuffer's cleanup later puts the handle
references.
Commit 1a148af06000 ("drm/gem-shmem: Use dma_buf from GEM object
instance") triggers the segmentation fault easily by using the dma-buf
field more widely. The underlying issue with reference counting has
been present before.
v2:
- acquire the handle instead of the BO (Christian)
- fix comment style (Christian)
- drop the Fixes tag (Christian)
- rename err_ gotos
- add missing Link tag

An example is shown below.\n\n[ 156.791968] ------------[ cut here ]------------\n[ 156.796830] WARNING: CPU: 2 PID: 2255 at drivers/dma-buf/dma-buf.c:1527 dma_buf_vmap+0x224/0x430\n[...]\n[ 156.942028] RIP: 0010:dma_buf_vmap+0x224/0x430\n[ 157.043420] Call Trace:\n[ 157.045898] \u003cTASK\u003e\n[ 157.048030] ? show_trace_log_lvl+0x1af/0x2c0\n[ 157.052436] ? show_trace_log_lvl+0x1af/0x2c0\n[ 157.056836] ? show_trace_log_lvl+0x1af/0x2c0\n[ 157.061253] ? drm_gem_shmem_vmap+0x74/0x710\n[ 157.065567] ? dma_buf_vmap+0x224/0x430\n[ 157.069446] ? __warn.cold+0x58/0xe4\n[ 157.073061] ? dma_buf_vmap+0x224/0x430\n[ 157.077111] ? report_bug+0x1dd/0x390\n[ 157.080842] ? handle_bug+0x5e/0xa0\n[ 157.084389] ? exc_invalid_op+0x14/0x50\n[ 157.088291] ? asm_exc_invalid_op+0x16/0x20\n[ 157.092548] ? dma_buf_vmap+0x224/0x430\n[ 157.096663] ? dma_resv_get_singleton+0x6d/0x230\n[ 157.101341] ? __pfx_dma_buf_vmap+0x10/0x10\n[ 157.105588] ? __pfx_dma_resv_get_singleton+0x10/0x10\n[ 157.110697] drm_gem_shmem_vmap+0x74/0x710\n[ 157.114866] drm_gem_vmap+0xa9/0x1b0\n[ 157.118763] drm_gem_vmap_unlocked+0x46/0xa0\n[ 157.123086] drm_gem_fb_vmap+0xab/0x300\n[ 157.126979] drm_atomic_helper_prepare_planes.part.0+0x487/0xb10\n[ 157.133032] ? lockdep_init_map_type+0x19d/0x880\n[ 157.137701] drm_atomic_helper_commit+0x13d/0x2e0\n[ 157.142671] ? drm_atomic_nonblocking_commit+0xa0/0x180\n[ 157.147988] drm_mode_atomic_ioctl+0x766/0xe40\n[...]\n[ 157.346424] ---[ end trace 0000000000000000 ]---\n\nAcquiring GEM handles for the framebuffer\u0027s GEM buffer objects prevents\nthis from happening.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: inline: fix len overflow in ext4_prepare_inline_data
When running the following code on an ext4 filesystem with inline_data
feature enabled, it will lead to the bug below.
fd = open("file1", O_RDWR | O_CREAT | O_TRUNC, 0666);
ftruncate(fd, 30);
pwrite(fd, "a", 1, (1UL << 40) + 5UL);
That happens because write_begin will succeed as when
ext4_generic_write_inline_data calls ext4_prepare_inline_data, pos + len
will be truncated, leading to ext4_prepare_inline_data parameter to be 6
instead of 0x10000000006.
Then, later when write_end is called, we hit:
BUG_ON(pos + len > EXT4_I(inode)->i_inline_size);
at ext4_write_inline_data.
Fix it by using a loff_t type for the len parameter in
ext4_prepare_inline_data instead of an unsigned int.

CVE-2025-38112 (GCVE-0-2025-38112)
Vulnerability from cvelistv5 – Published: 2025-07-03 08:35 – Updated: 2025-11-03 17:34

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: Fix TOCTOU issue in sk_is_readable()
sk->sk_prot->sock_is_readable is a valid function pointer when sk resides
in a sockmap. After the last sk_psock_put() (which usually happens when
socket is removed from sockmap), sk->sk_prot gets restored and
sk->sk_prot->sock_is_readable becomes NULL.
This makes sk_is_readable() racy, if the value of sk->sk_prot is reloaded
after the initial check. Which in turn may lead to a null pointer
dereference.
Ensure the function pointer does not turn NULL after the check.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sunrpc: handle SVC_GARBAGE during svc auth processing as auth error
tianshuo han reported a remotely-triggerable crash if the client sends a
kernel RPC server a specially crafted packet. If decoding the RPC reply
fails in such a way that SVC_GARBAGE is returned without setting the
rq_accept_statp pointer, then that pointer can be dereferenced and a
value stored there.
If it's the first time the thread has processed an RPC, then that
pointer will be set to NULL and the kernel will crash. In other cases,
it could create a memory scribble.
The server sunrpc code treats a SVC_GARBAGE return from svc_authenticate
or pg_authenticate as if it should send a GARBAGE_ARGS reply. RFC 5531
says that if authentication fails that the RPC should be rejected
instead with a status of AUTH_ERR.
Handle a SVC_GARBAGE return as an AUTH_ERROR, with a reason of
AUTH_BADCRED instead of returning GARBAGE_ARGS in that case. This
sidesteps the whole problem of touching the rpc_accept_statp pointer in
this situation and avoids the crash.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: sch_qfq: Fix race condition on qfq_aggregate
A race condition can occur when 'agg' is modified in qfq_change_agg
(called during qfq_enqueue) while other threads access it
concurrently. For example, qfq_dump_class may trigger a NULL
dereference, and qfq_delete_class may cause a use-after-free.
This patch addresses the issue by:
1. Moved qfq_destroy_class into the critical section.
2. Added sch_tree_lock protection to qfq_dump_class and
qfq_dump_class_stats.

CVE-2025-38352 (GCVE-0-2025-38352)
Vulnerability from cvelistv5 – Published: 2025-07-22 08:04 – Updated: 2025-11-03 17:37

Summary
In the Linux kernel, the following vulnerability has been resolved:
posix-cpu-timers: fix race between handle_posix_cpu_timers() and posix_cpu_timer_del()
If an exiting non-autoreaping task has already passed exit_notify() and
calls handle_posix_cpu_timers() from IRQ, it can be reaped by its parent
or debugger right after unlock_task_sighand().
If a concurrent posix_cpu_timer_del() runs at that moment, it won't be
able to detect timer->it.cpu.firing != 0: cpu_timer_task_rcu() and/or
lock_task_sighand() will fail.
Add the tsk->exit_state check into run_posix_cpu_timers() to fix this.
This fix is not needed if CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y, because
exit_task_work() is called before exit_notify(). But the check still
makes sense, task_work_add(&tsk->posix_cputimers_work.work) will fail
anyway in this case.
Severity ?
7.4 (High)

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/hugetlb: unshare page tables during VMA split, not before
Currently, __split_vma() triggers hugetlb page table unsharing through
vm_ops->may_split(). This happens before the VMA lock and rmap locks are
taken - which is too early, it allows racing VMA-locked page faults in our
process and racing rmap walks from other processes to cause page tables to
be shared again before we actually perform the split.
Fix it by explicitly calling into the hugetlb unshare logic from
__split_vma() in the same place where THP splitting also happens. At that
point, both the VMA and the rmap(s) are write-locked.
An annoying detail is that we can now call into the helper
hugetlb_unshare_pmds() from two different locking contexts:
1. from hugetlb_split(), holding:
- mmap lock (exclusively)
- VMA lock
- file rmap lock (exclusively)
2. hugetlb_unshare_all_pmds(), which I think is designed to be able to
call us with only the mmap lock held (in shared mode), but currently
only runs while holding mmap lock (exclusively) and VMA lock
Backporting note:
This commit fixes a racy protection that was introduced in commit
b30c14cd6102 ("hugetlb: unshare some PMDs when splitting VMAs"); that
commit claimed to fix an issue introduced in 5.13, but it should actually
also go all the way back.

Summary
In the Linux kernel, the following vulnerability has been resolved:
maple_tree: fix MA_STATE_PREALLOC flag in mas_preallocate()
Temporarily clear the preallocation flag when explicitly requesting
allocations. Pre-existing allocations are already counted against the
request through mas_node_count_gfp(), but the allocations will not happen
if the MA_STATE_PREALLOC flag is set. This flag is meant to avoid
re-allocating in bulk allocation mode, and to detect issues with
preallocation calculations.
The MA_STATE_PREALLOC flag should also always be set on zero allocations
so that detection of underflow allocations will print a WARN_ON() during
consumption.
User visible effect of this flaw is a WARN_ON() followed by a null pointer
dereference when subsequent requests for larger number of nodes is
ignored, such as the vma merge retry in mmap_region() caused by drivers
altering the vma flags (which happens in v6.6, at least)

Summary
In the Linux kernel, the following vulnerability has been resolved:
netlink: Fix wraparounds of sk->sk_rmem_alloc.
Netlink has this pattern in some places
if (atomic_read(&sk->sk_rmem_alloc) > sk->sk_rcvbuf)
atomic_add(skb->truesize, &sk->sk_rmem_alloc);
, which has the same problem fixed by commit 5a465a0da13e ("udp:
Fix multiple wraparounds of sk->sk_rmem_alloc.").
For example, if we set INT_MAX to SO_RCVBUFFORCE, the condition
is always false as the two operands are of int.
Then, a single socket can eat as many skb as possible until OOM
happens, and we can see multiple wraparounds of sk->sk_rmem_alloc.
Let's fix it by using atomic_add_return() and comparing the two
variables as unsigned int.
Before:
[root@fedora ~]# ss -f netlink
Recv-Q Send-Q Local Address:Port Peer Address:Port
-1668710080 0 rtnl:nl_wraparound/293 *
After:
[root@fedora ~]# ss -f netlink
Recv-Q Send-Q Local Address:Port Peer Address:Port
2147483072 0 rtnl:nl_wraparound/290 *

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Use memcpy() for BIOS version
The strlcat() with FORTIFY support is triggering a panic because it
thinks the target buffer will overflow although the correct target
buffer size is passed in.
Anyway, instead of memset() with 0 followed by a strlcat(), just use
memcpy() and ensure that the resulting buffer is NULL terminated.
BIOSVersion is only used for the lpfc_printf_log() which expects a
properly terminated string.
Severity ?
No CVSS data available.

The buggy address belongs to the object at ffff88810de2cb00
which belongs to the cache task_struct of size 3712
The buggy address is located 1992 bytes inside of
freed 3712-byte region [ffff88810de2cb00, ffff88810de2d980)
which is caused by the task_struct pointed to by sq->thread being
released while it is being used in the function
__io_uring_show_fdinfo(). Holding ctx->uring_lock does not prevent ehre
relase or exit of sq->thread.
Fix this by assigning and looking up ->thread under RCU, and grabbing a
reference to the task_struct. This e

Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring/msg_ring: ensure io_kiocb freeing is deferred for RCU
syzbot reports that defer/local task_work adding via msg_ring can hit
a request that has been freed:

which is supposed to be safe with how requests are allocated. But msg
ring requests alloc and free on their own, and hence must defer freeing
to a sane time.
Add an rcu_head and use kfree_rcu() in both spots where requests are
freed. Only the one in io_msg_tw_complete() is strictly required as it
has been visible on the other ring, but use it consistently in the other
spot as well.
This should not cause any other issues outside of KASAN rightfully
complaining about it.

CVE-2025-38283 (GCVE-0-2025-38283)
Vulnerability from cvelistv5 – Published: 2025-07-10 07:42 – Updated: 2025-07-28 04:17
VLAI?
EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
hisi_acc_vfio_pci: bugfix live migration function without VF device driver
If the VF device driver is not loaded in the Guest OS and we attempt to
perform device data migration, the address of the migrated data will
be NULL.
The live migration recovery operation on the destination side will
access a null address value, which will cause access errors.
Therefore, live migration of VMs without added VF device drivers
does not require device data migration.
In addition, when the queue address data obtained by the destination
is empty, device queue recovery processing will not be performed.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
coresight: prevent deactivate active config while enabling the config
While enable active config via cscfg_csdev_enable_active_config(),
active config could be deactivated via configfs' sysfs interface.
This could make UAF issue in below scenario:
CPU0 CPU1
(sysfs enable) load module
cscfg_load_config_sets()
activate config. // sysfs
(sys_active_cnt == 1)
...
cscfg_csdev_enable_active_config()
lock(csdev->cscfg_csdev_lock)
// here load config activate by CPU1
unlock(csdev->cscfg_csdev_lock)
deactivate config // sysfs
(sys_activec_cnt == 0)
cscfg_unload_config_sets()
unload module
// access to config_desc which freed
// while unloading module.
cscfg_csdev_enable_config
To address this, use cscfg_config_desc's active_cnt as a reference count
which will be holded when
- activate the config.
- enable the activated config.
and put the module reference when config_active_cnt == 0.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
aoe: clean device rq_list in aoedev_downdev()
An aoe device's rq_list contains accepted block requests that are
waiting to be transmitted to the aoe target. This queue was added as
part of the conversion to blk_mq. However, the queue was not cleaned out
when an aoe device is downed which caused blk_mq_freeze_queue() to sleep
indefinitely waiting for those requests to complete, causing a hang. This
fix cleans out the queue before calling blk_mq_freeze_queue().
Severity ?
No CVSS data available.
