Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: zynqmp_dma: In struct zynqmp_dma_chan fix desc_size data type
In zynqmp_dma_alloc/free_chan_resources functions there is a
potential overflow in the below expressions.
dma_alloc_coherent(chan->dev, (2 * chan->desc_size *
ZYNQMP_DMA_NUM_DESCS),
&chan->desc_pool_p, GFP_KERNEL);
dma_free_coherent(chan->dev,(2 * ZYNQMP_DMA_DESC_SIZE(chan) *
ZYNQMP_DMA_NUM_DESCS),
chan->desc_pool_v, chan->desc_pool_p);
The arguments desc_size and ZYNQMP_DMA_NUM_DESCS were 32 bit. Though
this overflow condition is not observed but it is a potential problem
in the case of 32-bit multiplication. Hence fix it by changing the
desc_size data type to size_t.
In addition to coverity fix it also reuse ZYNQMP_DMA_DESC_SIZE macro in
dma_alloc_coherent API argument.
Addresses-Coverity: Event overflow_before_widen.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: mediatek: mt8192-mt6359: Fix error handling in mt8192_mt6359_dev_probe
The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.
This function only calls of_node_put() in the regular path.
And it will cause refcount leak in error paths.
Fix this by calling of_node_put() in error handling too.
Severity ?
No CVSS data available.

CVE-2025-39880 (GCVE-0-2025-39880)
Vulnerability from cvelistv5 – Published: 2025-09-23 06:00 – Updated: 2025-11-03 17:44

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
libceph: fix invalid accesses to ceph_connection_v1_info
There is a place where generic code in messenger.c is reading and
another place where it is writing to con->v1 union member without
checking that the union member is active (i.e. msgr1 is in use).
On 64-bit systems, con->v1.auth_retry overlaps with con->v2.out_iter,
so such a read is almost guaranteed to return a bogus value instead of
0 when msgr2 is in use. This ends up being fairly benign because the
side effect is just the invalidation of the authorizer and successive
fetching of new tickets.
con->v1.connect_seq overlaps with con->v2.conn_bufs and the fact that
it's being written to can cause more serious consequences, but luckily
it's not something that happens often.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: ti-vpe: cal: Fix a NULL pointer dereference in cal_ctx_v4l2_init_formats()
In cal_ctx_v4l2_init_formats(), devm_kzalloc() is assigned to
ctx->active_fmt and there is a dereference of it after that, which could
lead to NULL pointer dereference on failure of devm_kzalloc().
Fix this bug by adding a NULL check of ctx->active_fmt.
This bug was found by a static analyzer.
Builds with 'make allyesconfig' show no new warnings, and our static
analyzer no longer warns about this code.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: accel: mma8452: use the correct logic to get mma8452_data
The original logic to get mma8452_data is wrong, the *dev point to
the device belong to iio_dev. we can't use this dev to find the
correct i2c_client. The original logic happen to work because it
finally use dev->driver_data to get iio_dev. Here use the API
to_i2c_client() is wrong and make reader confuse. To correct the
logic, it should be like this
struct mma8452_data *data = iio_priv(dev_get_drvdata(dev));
But after commit 8b7651f25962 ("iio: iio_device_alloc(): Remove
unnecessary self drvdata"), the upper logic also can't work.
When try to show the avialable scale in userspace, will meet kernel
dump, kernel handle NULL pointer dereference.
So use dev_to_iio_dev() to correct the logic.
Dual fixes tags as the second reflects when the bug was exposed, whilst
the first reflects when the original bug was introduced.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ceph: fix crash after fscrypt_encrypt_pagecache_blocks() error
The function move_dirty_folio_in_page_array() was created by commit
ce80b76dd327 ("ceph: introduce ceph_process_folio_batch() method") by
moving code from ceph_writepages_start() to this function.
This new function is supposed to return an error code which is checked
by the caller (now ceph_process_folio_batch()), and on error, the
caller invokes redirty_page_for_writepage() and then breaks from the
loop.
However, the refactoring commit has gone wrong, and it by accident, it
always returns 0 (= success) because it first NULLs the pointer and
then returns PTR_ERR(NULL) which is always 0. This means errors are
silently ignored, leaving NULL entries in the page array, which may
later crash the kernel.
The simple solution is to call PTR_ERR() before clearing the pointer.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ipv6: unexport __init-annotated seg6_hmac_init()
EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.
modpost used to detect it, but it has been broken for a decade.
Recently, I fixed modpost so it started to warn it again, then this
showed up in linux-next builds.
There are two ways to fix it:
- Remove __init
- Remove EXPORT_SYMBOL
I chose the latter for this case because the caller (net/ipv6/seg6.c)
and the callee (net/ipv6/seg6_hmac.c) belong to the same module.
It seems an internal function call in ipv6.ko.
Severity ?

CVE-2025-39879 (GCVE-0-2025-39879)
Vulnerability from cvelistv5 – Published: 2025-09-23 06:00 – Updated: 2025-09-29 06:01

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
ceph: always call ceph_shift_unused_folios_left()
The function ceph_process_folio_batch() sets folio_batch entries to
NULL, which is an illegal state. Before folio_batch_release() crashes
due to this API violation, the function ceph_shift_unused_folios_left()
is supposed to remove those NULLs from the array.
However, since commit ce80b76dd327 ("ceph: introduce
ceph_process_folio_batch() method"), this shifting doesn't happen
anymore because the "for" loop got moved to ceph_process_folio_batch(),
and now the `i` variable that remains in ceph_writepages_start()
doesn't get incremented anymore, making the shifting effectively
unreachable much of the time.
Later, commit 1551ec61dc55 ("ceph: introduce ceph_submit_write()
method") added more preconditions for doing the shift, replacing the
`i` check (with something that is still just as broken):
- if ceph_process_folio_batch() fails, shifting never happens
- if ceph_move_dirty_page_in_page_array() was never called (because
ceph_process_folio_batch() has returned early for some of various
reasons), shifting never happens
- if `processed_in_fbatch` is zero (because ceph_process_folio_batch()
has returned early for some of the reasons mentioned above or
because ceph_move_dirty_page_in_page_array() has failed), shifting
never happens
Since those two commits, any problem in ceph_process_folio_batch()
could crash the kernel, e.g. this way:

Call Trace:
<TASK>
ceph_writepages_start+0xeb9/0x1410
The crash can be reproduced easily by changing the
ceph_check_page_before_write() return value to `-E2BIG`.
(Interestingly, the crash happens only if `huge_zero_folio` has
already been allocated; without `huge_zero_folio`,
is_huge_zero_folio(NULL) returns true and folios_put_refs() skips NULL
entries instead of dereferencing them. That makes reproducing the bug
somewhat unreliable. See
https://lore.kernel.org/20250826231626.218675-1-max.kellermann@ionos.com
for a discussion of this detail.)
My suggestion is to move the ceph_shift_unused_folios_left() to right
after ceph_process_folio_batch() to ensure it always gets called to
fix up the illegal folio_batch state.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipmi:ipmb: Fix refcount leak in ipmi_ipmb_probe
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
Severity ?

CVE-2022-49246 (GCVE-0-2022-49246)
Vulnerability from cvelistv5 – Published: 2025-02-26 01:56 – Updated: 2025-05-04 08:33

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: atmel: Fix error handling in snd_proto_probe
The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.
This function only calls of_node_put() in the regular path.
And it will cause refcount leak in error paths.
Fix this by calling of_node_put() in error handling too.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/64s: Don't use DSISR for SLB faults
Since commit 46ddcb3950a2 ("powerpc/mm: Show if a bad page fault on data
is read or write.") we use page_fault_is_write(regs->dsisr) in
__bad_page_fault() to determine if the fault is for a read or write, and
change the message printed accordingly.
But SLB faults, aka Data Segment Interrupts, don't set DSISR (Data
Storage Interrupt Status Register) to a useful value. All ISA versions
from v2.03 through v3.1 specify that the Data Segment Interrupt sets
DSISR "to an undefined value". As far as I can see there's no mention of
SLB faults setting DSISR in any BookIV content either.
This manifests as accesses that should be a read being incorrectly
reported as writes, for example, using the xmon "dump" command:
0:mon> d 0x5deadbeef0000000
5deadbeef0000000
[359526.415354][ C6] BUG: Unable to handle kernel data access on write at 0x5deadbeef0000000
[359526.415611][ C6] Faulting instruction address: 0xc00000000010a300
cpu 0x6: Vector: 380 (Data SLB Access) at [c00000000ffbf400]
pc: c00000000010a300: mread+0x90/0x190
If we disassemble the PC, we see a load instruction:
0:mon> di c00000000010a300
c00000000010a300 89490000 lbz r10,0(r9)
We can also see in exceptions-64s.S that the data_access_slb block
doesn't set IDSISR=1, which means it doesn't load DSISR into pt_regs. So
the value we're using to determine if the fault is a read/write is some
stale value in pt_regs from a previous page fault.
Rework the printing logic to separate the SLB fault case out, and only
print read/write in the cases where we can determine it.
The result looks like eg:
0:mon> d 0x5deadbeef0000000
5deadbeef0000000
[ 721.779525][ C6] BUG: Unable to handle kernel data access at 0x5deadbeef0000000

Summary
In the Linux kernel, the following vulnerability has been resolved:
igb: Fix NULL pointer dereference in ethtool loopback test
The igb driver currently causes a NULL pointer dereference when executing
the ethtool loopback test. This occurs because there is no associated
q_vector for the test ring when it is set up, as interrupts are typically
not added to the test rings.
Since commit 5ef44b3cb43b removed the napi_id assignment in
__xdp_rxq_info_reg(), there is no longer a need to pass a napi_id to it.
Therefore, simply use 0 as the last parameter.

Summary
In the Linux kernel, the following vulnerability has been resolved:
watch_queue: Actually free the watch
free_watch() does everything barring actually freeing the watch object. Fix
this by adding the missing kfree.
kmemleak produces a report something like the following. Note that as an
address can be seen in the first word, the watch would appear to have gone
through call_rcu().

ocfs2_fiemap() takes a read lock of the ip_alloc_sem semaphore (since
v2.6.22-527-g7307de80510a) and calls fiemap_fill_next_extent() to read the
extent list of this running mmap executable. The user supplied buffer to
hold the fiemap information page faults calling ocfs2_page_mkwrite() which
will take a write lock (since v2.6.27-38-g00dc417fa3e7) of the same
semaphore. This recursive semaphore will hold filesystem locks and causes
a hang of the fileystem.
The ip_alloc_sem protects the inode extent list and size. Release the
read semphore before calling fiemap_fill_next_extent() in ocfs2_fiemap()
and ocfs2_fiemap_inline(). This does an unnecessary semaphore lock/unlock
on the last extent but simplifies the error path.

The user supplied buffer to\nhold the fiemap information page faults calling ocfs2_page_mkwrite() which\nwill take a write lock (since v2.6.27-38-g00dc417fa3e7) of the same\nsemaphore. This recursive semaphore will hold filesystem locks and causes\na hang of the fileystem.\n\nThe ip_alloc_sem protects the inode extent list and size. Release the\nread semphore before calling fiemap_fill_next_extent() in ocfs2_fiemap()\nand ocfs2_fiemap_inline(). This does an unnecessary semaphore lock/unlock\non the last extent but simplifies the error path."

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix a btf decl_tag bug when tagging a function
syzbot reported a btf decl_tag bug with stack trace below:
general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] PREEMPT SMP KASAN

The kasan error is triggered with an illegal BTF like below:
type 0: void
type 1: int
type 2: decl_tag to func type 3
type 3: func to func_proto type 8
The total number of types is 4 and the type 3 is illegal
since its func_proto type is out of range.
Currently, the target type of decl_tag can be struct/union, var or func.
Both struct/union and var implemented their own 'resolve' callback functions
and hence handled properly in kernel.
But func type doesn't have 'resolve' callback function. When
btf_decl_tag_resolve() tries to check func type, it tries to get
vlen of its func_proto type, which triggered the above kasan error.
To fix the issue, btf_decl_tag_resolve() needs to do btf_func_check()
before trying to accessing func_proto type.
In the current implementation, func type is checked with
btf_func_check() in the main checking function btf_check_all_types().
To fix the above kasan issue, let us implement 'resolve' callback
func type properly. The 'resolve' callback will be also called
in btf_check_all_types() for func types.

dmaengine: ti: edma: Fix memory allocation size for queue_priority_map
Fix a critical memory allocation bug in edma_setup_from_hw() where
queue_priority_map was allocated with insufficient memory. The code
declared queue_priority_map as s8 (*)[2] (pointer to array of 2 s8),
but allocated memory using sizeof(s8) instead of the correct size.
This caused out-of-bounds memory writes when accessing:
queue_priority_map[i][0] = i;
queue_priority_map[i][1] = i;
The bug manifested as kernel crashes with "Oops - undefined instruction"
on ARM platforms (BeagleBoard-X15) during EDMA driver probe, as the
memory corruption triggered kernel hardening features on Clang.
Change the allocation to use sizeof(*queue_priority_map) which
automatically gets the correct size for the 2D array structure.

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: fix potential OF node use-after-free
The for_each_child_of_node() helper drops the reference it takes to each
node as it iterates over children and an explicit of_node_put() is only
needed when exiting the loop early.
Drop the recently introduced bogus additional reference count decrement
at each iteration that could potentially lead to a use-after-free.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: wc938x: fix accessing array out of bounds for enum type
Accessing enums using integer would result in array out of bounds access
on platforms like aarch64 where sizeof(long) is 8 compared to enum size
which is 4 bytes.
Fix this by using enumerated items instead of integers.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: fix tcp_mtup_probe_success vs wrong snd_cwnd
syzbot got a new report [1] finally pointing to a very old bug,
added in initial support for MTU probing.
tcp_mtu_probe() has checks about starting an MTU probe if
tcp_snd_cwnd(tp) >= 11.
But nothing prevents tcp_snd_cwnd(tp) to be reduced later
and before the MTU probe succeeds.
This bug would lead to potential zero-divides.
Debugging added in commit 40570375356c ("tcp: add accessors
to read/set tp->snd_cwnd") has paid off :)
While we are at it, address potential overflows in this code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
driver core: Fix wait_for_device_probe() & deferred_probe_timeout interaction
Mounting NFS rootfs was timing out when deferred_probe_timeout was
non-zero [1]. This was because ip_auto_config() initcall times out
waiting for the network interfaces to show up when
deferred_probe_timeout was non-zero. While ip_auto_config() calls
wait_for_device_probe() to make sure any currently running deferred
probe work or asynchronous probe finishes, that wasn't sufficient to
account for devices being deferred until deferred_probe_timeout.
Commit 35a672363ab3 ("driver core: Ensure wait_for_device_probe() waits
until the deferred_probe_timeout fires") tried to fix that by making
sure wait_for_device_probe() waits for deferred_probe_timeout to expire
before returning.
However, if wait_for_device_probe() is called from the kernel_init()
context:
- Before deferred_probe_initcall() [2], it causes the boot process to
hang due to a deadlock.
- After deferred_probe_initcall() [3], it blocks kernel_init() from
continuing till deferred_probe_timeout expires and beats the point of
deferred_probe_timeout that's trying to wait for userspace to load
modules.
Neither of this is good. So revert the changes to
wait_for_device_probe().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: dlmfs: fix error handling of user_dlm_destroy_lock
When user_dlm_destroy_lock failed, it didn't clean up the flags it set
before exit. For USER_LOCK_IN_TEARDOWN, if this function fails because of
lock is still in used, next time when unlink invokes this function, it
will return succeed, and then unlink will remove inode and dentry if lock
is not in used(file closed), but the dlm lock is still linked in dlm lock
resource, then when bast come in, it will trigger a panic due to
user-after-free. See the following panic call trace. To fix this,
USER_LOCK_IN_TEARDOWN should be reverted if fail. And also error should
be returned if USER_LOCK_IN_TEARDOWN is set to let user know that unlink
fail.
For the case of ocfs2_dlm_unlock failure, besides USER_LOCK_IN_TEARDOWN,
USER_LOCK_BUSY is also required to be cleared. Even though spin lock is
released in between, but USER_LOCK_IN_TEARDOWN is still set, for
USER_LOCK_BUSY, if before every place that waits on this flag,
USER_LOCK_IN_TEARDOWN is checked to bail out, that will make sure no flow
waits on the busy flag set by user_dlm_destroy_lock(), then we can
simplely revert USER_LOCK_BUSY when ocfs2_dlm_unlock fails. Fix
user_dlm_cluster_lock() which is the only function not following this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: idxd: Fix double free in idxd_setup_wqs()
The clean up in idxd_setup_wqs() has had a couple bugs because the error
handling is a bit subtle. It's simpler to just re-write it in a cleaner
way. The issues here are:
1) If "idxd->max_wqs" is <= 0 then we call put_device(conf_dev) when
"conf_dev" hasn't been initialized.
2) If kzalloc_node() fails then again "conf_dev" is invalid. It's
either uninitialized or it points to the "conf_dev" from the
previous iteration so it leads to a double free.
It's better to free partial loop iterations within the loop and then
the unwinding at the end can handle whole loop iterations. I also
renamed the labels to describe what the goto does and not where the goto
was located.
Severity ?
No CVSS data available.

Kernel Offset: 0x31c00000 from 0xffffffff81000000 (relocation range: 0xffffffff80000000-0xffffffffbfffffff)
---[ end Kernel panic - not syncing: Fatal exception ]---
The root cause is that unpoison_memory() tries to check the PG_HWPoison
flags of an uninitialized page. So VM_BUG_ON_PAGE(PagePoisoned(page)) is
triggered. This can be reproduced by below steps:
1.Offline memory block:
echo offline > /sys/devices/system/memory/memory12/state
2.Get offlined memory pfn:
page-types -b n -rlN
3.Write pfn to unpoison-pfn
echo <pfn> > /sys/kernel/debug/hwpoison/unpoison-pfn
This scenario can be identified by pfn_to_online_page() returning NULL.
And ZONE_DEVICE pages are never expected, so we can simply fail if
pfn_to_online_page() == NULL to fix the bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Tell memcg to use allow_spinning=false path in bpf_timer_init()
Currently, calling bpf_map_kmalloc_node() from __bpf_async_init() can
cause various locking issues; see the following stack trace (edited for
style) as one example:
...
[10.011566] do_raw_spin_lock.cold
[10.011570] try_to_wake_up (5) double-acquiring the same
[10.011575] kick_pool rq_lock, causing a hardlockup
[10.011579] __queue_work
[10.011582] queue_work_on
[10.011585] kernfs_notify
[10.011589] cgroup_file_notify
[10.011593] try_charge_memcg (4) memcg accounting raises an
[10.011597] obj_cgroup_charge_pages MEMCG_MAX event
[10.011599] obj_cgroup_charge_account
[10.011600] __memcg_slab_post_alloc_hook
[10.011603] __kmalloc_node_noprof
...
[10.011611] bpf_map_kmalloc_node
[10.011612] __bpf_async_init
[10.011615] bpf_timer_init (3) BPF calls bpf_timer_init()
[10.011617] bpf_prog_xxxxxxxxxxxxxxxx_fcg_runnable
[10.011619] bpf__sched_ext_ops_runnable
[10.011620] enqueue_task_scx (2) BPF runs with rq_lock held
[10.011622] enqueue_task
[10.011626] ttwu_do_activate
[10.011629] sched_ttwu_pending (1) grabs rq_lock
...
The above was reproduced on bpf-next (b338cf849ec8) by modifying
./tools/sched_ext/scx_flatcg.bpf.c to call bpf_timer_init() during
ops.runnable(), and hacking the memcg accounting code a bit to make
a bpf_timer_init() call more likely to raise an MEMCG_MAX event.
We have also run into other similar variants (both internally and on
bpf-next), including double-acquiring cgroup_file_kn_lock, the same
worker_pool::lock, etc.
As suggested by Shakeel, fix this by using __GFP_HIGH instead of
GFP_ATOMIC in __bpf_async_init(), so that e.g. if try_charge_memcg()
raises an MEMCG_MAX event, we call __memcg_memory_event() with
@allow_spinning=false and avoid calling cgroup_file_notify() there.
Depends on mm patch
"memcg: skip cgroup_file_notify if spinning is not allowed":

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing/osnoise: Fix null-ptr-deref in bitmap_parselist()
A crash was observed with the following output:
BUG: kernel NULL pointer dereference, address: 0000000000000010
Oops: Oops: 0000 [#1] SMP NOPTI
CPU: 2 UID: 0 PID: 92 Comm: osnoise_cpus Not tainted 6.17.0-rc4-00201-gd69eb204c255 #138 PREEMPT(voluntary)
RIP: 0010:bitmap_parselist+0x53/0x3e0
Call Trace:
<TASK>
osnoise_cpus_write+0x7a/0x190

ksys_write+0x60/0xd0
do_syscall_64+0xa4/0x260
entry_SYSCALL_64_after_hwframe+0x77/0x7f
</TASK>
This issue can be reproduced by below code:
fd=open("/sys/kernel/debug/tracing/osnoise/cpus", O_WRONLY);
write(fd, "0-2", 0);
When user pass 'count=0' to osnoise_cpus_write(), kmalloc() will return
ZERO_SIZE_PTR (16) and cpulist_parse() treat it as a normal value, which
trigger the null pointer dereference. Add check for the parameter 'count'.
Severity ?

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/gem: add missing boundary check in vm_access
A missing bounds check in vm_access() can lead to an out-of-bounds read
or write in the adjacent memory area, since the len attribute is not
validated before the memcpy later in the function, potentially hitting:

Summary
In the Linux kernel, the following vulnerability has been resolved:
uaccess: fix integer overflow on access_ok()
Three architectures check the end of a user access against the
address limit without taking a possible overflow into account.
Passing a negative length or another overflow in here returns
success when it should not.
Use the most common correct implementation here, which optimizes
for a constant 'size' argument, and turns the common case into a
single comparison.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dlm: fix plock invalid read
This patch fixes an invalid read showed by KASAN. A unlock will allocate a
"struct plock_op" and a followed send_op() will append it to a global
send_list data structure. In some cases a followed dev_read() moves it
to recv_list and dev_write() will cast it to "struct plock_xop" and access
fields which are only available in those structures. At this point an
invalid read happens by accessing those fields.
To fix this issue the "callback" field is moved to "struct plock_op" to
indicate that a cast to "plock_xop" is allowed and does the additional
"plock_xop" handling if set.
Example of the KASAN output which showed the invalid read:

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndlm: fix plock invalid read\n\nThis patch fixes an invalid read showed by KASAN. A unlock will allocate a\n\"struct plock_op\" and a followed send_op() will append it to a global\nsend_list data structure. In some cases a followed dev_read() moves it\nto recv_list and dev_write() will cast it to \"struct plock_xop\" and access\nfields which are only available in those structures. At this point an\ninvalid read happens by accessing those fields.\n\nTo fix this issue the \"callback\" field is moved to \"struct plock_op\" to\nindicate that a cast to \"plock_xop\" is allowed and does the additional\n\"plock_xop\" handling if set.\n\nExample of the KASAN output which showed the invalid read:\n\n[ 2064.296453] ==================================================================\n[ 2064.304852] BUG: KASAN: slab-out-of-bounds in dev_write+0x52b/0x5a0 [dlm]\n[ 2064.306491] Read of size 8 at addr ffff88800ef227d8 by task dlm_controld/7484\n[ 2064.308168]\n[ 2064.308575] CPU: 0 PID: 7484 Comm: dlm_controld Kdump: loaded Not tainted 5.14.0+ #9\n[ 2064.310292] Hardware name: Red Hat KVM, BIOS 0.5.1 01/01/2011\n[ 2064.311618] Call Trace:\n[ 2064.312218] dump_stack_lvl+0x56/0x7b\n[ 2064.313150] print_address_description.constprop.8+0x21/0x150\n[ 2064.314578] ? dev_write+0x52b/0x5a0 [dlm]\n[ 2064.315610] ? dev_write+0x52b/0x5a0 [dlm]\n[ 2064.316595] kasan_report.cold.14+0x7f/0x11b\n[ 2064.317674] ? dev_write+0x52b/0x5a0 [dlm]\n[ 2064.318687] dev_write+0x52b/0x5a0 [dlm]\n[ 2064.319629] ? dev_read+0x4a0/0x4a0 [dlm]\n[ 2064.320713] ? bpf_lsm_kernfs_init_security+0x10/0x10\n[ 2064.321926] vfs_write+0x17e/0x930\n[ 2064.322769] ? __fget_light+0x1aa/0x220\n[ 2064.323753] ksys_write+0xf1/0x1c0\n[ 2064.324548] ? __ia32_sys_read+0xb0/0xb0\n[ 2064.325464] do_syscall_64+0x3a/0x80\n[ 2064.326387] entry_SYSCALL_64_after_hwframe+0x44/0xae\n[ 2064.327606] RIP: 0033:0x7f807e4ba96f\n[ 2064.328470] Code: 89 54 24 18 48 89 74 24 10 89 7c 24 08 e8 39 87 f8 ff 48 8b 54 24 18 48 8b 74 24 10 41 89 c0 8b 7c 24 08 b8 01 00 00 00 0f 05 \u003c48\u003e 3d 00 f0 ff ff 77 31 44 89 c7 48 89 44 24 08 e8 7c 87 f8 ff 48\n[ 2064.332902] RSP: 002b:00007ffd50cfe6e0 EFLAGS: 00000293 ORIG_RAX: 0000000000000001\n[ 2064.334658] RAX: ffffffffffffffda RBX: 000055cc3886eb30 RCX: 00007f807e4ba96f\n[ 2064.336275] RDX: 0000000000000040 RSI: 00007ffd50cfe7e0 RDI: 0000000000000010\n[ 2064.337980] RBP: 00007ffd50cfe7e0 R08: 0000000000000000 R09: 0000000000000001\n[ 2064.339560] R10: 000055cc3886eb30 R11: 0000000000000293 R12: 000055cc3886eb80\n[ 2064.341237] R13: 000055cc3886eb00 R14: 000055cc3886f590 R15: 0000000000000001\n[ 2064.342857]\n[ 2064.343226] Allocated by task 12438:\n[ 2064.344057] kasan_save_stack+0x1c/0x40\n[ 2064.345079] __kasan_kmalloc+0x84/0xa0\n[ 2064.345933] kmem_cache_alloc_trace+0x13b/0x220\n[ 2064.346953] dlm_posix_unlock+0xec/0x720 [dlm]\n[ 2064.348811] do_lock_file_wait.part.32+0xca/0x1d0\n[ 2064.351070] fcntl_setlk+0x281/0xbc0\n[ 2064.352879] do_fcntl+0x5e4/0xfe0\n[ 2064.354657] __x64_sys_fcntl+0x11f/0x170\n[ 2064.356550] do_syscall_64+0x3a/0x80\n[ 2064.358259] entry_SYSCALL_64_after_hwframe+0x44/0xae\n[ 2064.360745]\n[ 2064.361511] Last potentially related work creation:\n[ 2064.363957] kasan_save_stack+0x1c/0x40\n[ 2064.365811] __kasan_record_aux_stack+0xaf/0xc0\n[ 2064.368100] call_rcu+0x11b/0xf70\n[ 2064.369785] dlm_process_incoming_buffer+0x47d/0xfd0 [dlm]\n[ 2064.372404] receive_from_sock+0x290/0x770 [dlm]\n[ 2064.374607] process_recv_sockets+0x32/0x40 [dlm]\n[ 2064.377290] process_one_work+0x9a8/0x16e0\n[ 2064.379357] worker_thread+0x87/0xbf0\n[ 2064.381188] kthread+0x3ac/0x490\n[ 2064.383460] ret_from_fork+0x22/0x30\n[ 2064.385588]\n[ 2064.386518] Second to last potentially related work creation:\n[ 2064.389219] kasan_save_stack+0x1c/0x40\n[ 2064.391043] __kasan_record_aux_stack+0xaf/0xc0\n[ 2064.393303] call_rcu+0x11b/0xf70\n[ 2064.394885] dlm_process_incoming_buffer+0x47d/0xfd0 [dlm]\n[ 2064.397694] receive_from_sock+0x290/0x770 \n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: xilinx_can: xcan_write_frame(): fix use-after-free of transmitted SKB
can_put_echo_skb() takes ownership of the SKB and it may be freed
during or after the call.
However, xilinx_can xcan_write_frame() keeps using SKB after the call.
Fix that by only calling can_put_echo_skb() after the code is done
touching the SKB.
The tx_lock is held for the entire xcan_write_frame() execution and
also on the can_get_echo_skb() side so the order of operations does not
matter.
An earlier fix commit 3d3c817c3a40 ("can: xilinx_can: Fix usage of skb
memory") did not move the can_put_echo_skb() call far enough.
[mkl: add "commit" in front of sha1 in patch description]

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: mdio: unexport __init-annotated mdio_bus_init()
EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.
modpost used to detect it, but it has been broken for a decade.
Recently, I fixed modpost so it started to warn it again, then this
showed up in linux-next builds.
There are two ways to fix it:
- Remove __init
- Remove EXPORT_SYMBOL
I chose the latter for this case because the only in-tree call-site,
drivers/net/phy/phy_device.c is never compiled as modular.
(CONFIG_PHYLIB is boolean)
Severity ?

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Fix double uncharge the mem of sk_msg
If tcp_bpf_sendmsg is running during a tear down operation, psock may be
freed.
tcp_bpf_sendmsg()
tcp_bpf_send_verdict()
sk_msg_return()
tcp_bpf_sendmsg_redir()
unlikely(!psock))
sk_msg_free()
The mem of msg has been uncharged in tcp_bpf_send_verdict() by
sk_msg_return(), and would be uncharged by sk_msg_free() again. When psock
is null, we can simply returning an error code, this would then trigger
the sk_msg_free_nocharge in the error path of __SK_REDIRECT and would have
the side effect of throwing an error up to user space. This would be a
slight change in behavior from user side but would look the same as an
error if the redirect on the socket threw an error.
This issue can cause the following info:
WARNING: CPU: 0 PID: 2136 at net/ipv4/af_inet.c:155 inet_sock_destruct+0x13c/0x260

Summary
In the Linux kernel, the following vulnerability has been resolved:
erofs: fix runtime warning on truncate_folio_batch_exceptionals()
Commit 0e2f80afcfa6("fs/dax: ensure all pages are idle prior to
filesystem unmount") introduced the WARN_ON_ONCE to capture whether
the filesystem has removed all DAX entries or not and applied the
fix to xfs and ext4.
Apply the missed fix on erofs to fix the runtime warning:

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: add accessors to read/set tp->snd_cwnd
We had various bugs over the years with code
breaking the assumption that tp->snd_cwnd is greater
than zero.
Lately, syzbot reported the WARN_ON_ONCE(!tp->prior_cwnd) added
in commit 8b8a321ff72c ("tcp: fix zero cwnd in tcp_cwnd_reduction")
can trigger, and without a repro we would have to spend
considerable time finding the bug.
Instead of complaining too late, we want to catch where
and when tp->snd_cwnd is set to an illegal value.
Severity ?
No CVSS data available.

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: xfrm: unexport __init-annotated xfrm4_protocol_init()
EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.
modpost used to detect it, but it has been broken for a decade.
Recently, I fixed modpost so it started to warn it again, then this
showed up in linux-next builds.
There are two ways to fix it:
- Remove __init
- Remove EXPORT_SYMBOL
I chose the latter for this case because the only in-tree call-site,
net/ipv4/xfrm4_policy.c is never compiled as modular.
(CONFIG_XFRM is boolean)
Severity ?
No CVSS data available.

Above issue may happen as follows:
-------------------------------------
ext4_fill_super
ext4_enable_quotas
ext4_quota_enable
ext4_iget
__ext4_iget
ext4_ext_check_inode
ext4_ext_check
__ext4_ext_check
ext4_valid_extent_entries
Check for overlapping extents does't take effect
dquot_enable
vfs_load_quota_inode
v2_check_quota_file
v2_read_header
ext4_quota_read
ext4_bread
ext4_getblk
ext4_map_blocks
ext4_ext_map_blocks
ext4_find_extent
ext4_cache_extents
ext4_es_cache_extent
ext4_es_cache_extent
__es_tree_search
ext4_es_end
BUG_ON(es->es_lblk + es->es_len < es->es_lblk)
The error ext4 extents is as follows:
0af3 0300 0400 0000 00000000 extent_header
00000000 0100 0000 12000000 extent1
00000000 0100 0000 18000000 extent2
02000000 0400 0000 14000000 extent3
In the ext4_valid_extent_entries function,
if prev is 0, no error is returned even if lblock<=prev.
This was intended to skip the check on the first extent, but
in the error image above, prev=0+1-1=0 when checking the second extent,
so even though lblock<=prev, the function does not return an error.
As a result, bug_ON occurs in __es_tree_search and the system panics.
To solve this problem, we only need to check that:
1. The lblock of the first extent is not less than 0.
2. The lblock of the next extent is not less than
the next block of the previous extent.
The same applies to extent_idx.

Summary
In the Linux kernel, the following vulnerability has been resolved:
hsr: hold rcu and dev lock for hsr_get_port_ndev
hsr_get_port_ndev calls hsr_for_each_port, which need to hold rcu lock.
On the other hand, before return the port device, we need to hold the
device reference to avoid UaF in the caller function.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: pcm: Fix potential AB/BA lock with buffer_mutex and mmap_lock
syzbot caught a potential deadlock between the PCM
runtime->buffer_mutex and the mm->mmap_lock. It was brought by the
recent fix to cover the racy read/write and other ioctls, and in that
commit, I overlooked a (hopefully only) corner case that may take the
revert lock, namely, the OSS mmap. The OSS mmap operation
exceptionally allows to re-configure the parameters inside the OSS
mmap syscall, where mm->mmap_mutex is already held. Meanwhile, the
copy_from/to_user calls at read/write operations also take the
mm->mmap_lock internally, hence it may lead to a AB/BA deadlock.
A similar problem was already seen in the past and we fixed it with a
refcount (in commit b248371628aa). The former fix covered only the
call paths with OSS read/write and OSS ioctls, while we need to cover
the concurrent access via both ALSA and OSS APIs now.
This patch addresses the problem above by replacing the buffer_mutex
lock in the read/write operations with a refcount similar as we've
used for OSS. The new field, runtime->buffer_accessing, keeps the
number of concurrent read/write operations. Unlike the former
buffer_mutex protection, this protects only around the
copy_from/to_user() calls; the other codes are basically protected by
the PCM stream lock. The refcount can be a negative, meaning blocked
by the ioctls. If a negative value is seen, the read/write aborts
with -EBUSY. In the ioctl side, OTOH, they check this refcount, too,
and set to a negative value for blocking unless it's already being
accessed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix subvolume deletion lockup caused by inodes xarray race
There is a race condition between inode eviction and inode caching that
can cause a live struct btrfs_inode to be missing from the root->inodes
xarray. Specifically, there is a window during evict() between the inode
being unhashed and deleted from the xarray. If btrfs_iget() is called
for the same inode in that window, it will be recreated and inserted
into the xarray, but then eviction will delete the new entry, leaving
nothing in the xarray:
Thread 1 Thread 2
---------------------------------------------------------------
evict()
remove_inode_hash()
btrfs_iget_path()
btrfs_iget_locked()
btrfs_read_locked_inode()
btrfs_add_inode_to_root()
destroy_inode()
btrfs_destroy_inode()
btrfs_del_inode_from_root()
__xa_erase
In turn, this can cause issues for subvolume deletion. Specifically, if
an inode is in this lost state, and all other inodes are evicted, then
btrfs_del_inode_from_root() will call btrfs_add_dead_root() prematurely.
If the lost inode has a delayed_node attached to it, then when
btrfs_clean_one_deleted_snapshot() calls btrfs_kill_all_delayed_nodes(),
it will loop forever because the delayed_nodes xarray will never become
empty (unless memory pressure forces the inode out). We saw this
manifest as soft lockups in production.
Fix it by only deleting the xarray entry if it matches the given inode
(using __xa_cmpxchg()).

CVE-2022-49271 (GCVE-0-2022-49271)
Vulnerability from cvelistv5 – Published: 2025-02-26 01:56 – Updated: 2025-10-29 10:49

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: prevent bad output lengths in smb2_ioctl_query_info()
When calling smb2_ioctl_query_info() with
smb_query_info::flags=PASSTHRU_FSCTL and
smb_query_info::output_buffer_length=0, the following would return
0x10
buffer = memdup_user(arg + sizeof(struct smb_query_info),
qi.output_buffer_length);
if (IS_ERR(buffer)) {
kfree(vars);
return PTR_ERR(buffer);
}
rather than a valid pointer thus making IS_ERR() check fail. This
would then cause a NULL ptr deference in @buffer when accessing it
later in smb2_ioctl_query_ioctl(). While at it, prevent having a
@buffer smaller than 8 bytes to correctly handle SMB2_SET_INFO
FileEndOfFileInformation requests when
smb_query_info::flags=PASSTHRU_SET_INFO.
Here is a small C reproducer which triggers a NULL ptr in @buffer when
passing an invalid smb_query_info::flags
#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
#include <unistd.h>
#include <fcntl.h>
#include <sys/ioctl.h>

#define QUERY_INFO 0xc018cf07
int main(int argc, char *argv[])
{
int fd;
if (argc < 2)
exit(1);
fd = open(argv[1], O_RDONLY);
if (fd == -1)
die("open");
if (ioctl(fd, QUERY_INFO, (uint32_t[]) { 0, 0, 0, 4, 0, 0}) == -1)
die("ioctl");
close(fd);
return 0;

Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: fix crash when mount with quota enabled
There is a reported crash when mounting ocfs2 with quota enabled.
RIP: 0010:ocfs2_qinfo_lock_res_init+0x44/0x50 [ocfs2]
Call Trace:
ocfs2_local_read_info+0xb9/0x6f0 [ocfs2]

vfs_get_tree+0x25/0xb0
path_mount+0x465/0xac0
__x64_sys_mount+0x103/0x140
It is caused by when initializing dqi_gqlock, the corresponding dqi_type
and dqi_sb are not properly initialized.
This issue is introduced by commit 6c85c2c72819, which wants to avoid
accessing uninitialized variables in error cases. So make global quota
info properly initialized.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: Avoid cross-chip syncing of VLAN filtering
Changes to VLAN filtering are not applicable to cross-chip
notifications.
On a system like this:
.-----. .-----. .-----.
| sw1 +---+ sw2 +---+ sw3 |
'-1-2-' '-1-2-' '-1-2-'
Before this change, upon sw1p1 leaving a bridge, a call to
dsa_port_vlan_filtering would also be made to sw2p1 and sw3p1.
In this scenario:
.---------. .-----. .-----.
| sw1 +---+ sw2 +---+ sw3 |
'-1-2-3-4-' '-1-2-' '-1-2-'
When sw1p4 would leave a bridge, dsa_port_vlan_filtering would be
called for sw2 and sw3 with a non-existing port - leading to array
out-of-bounds accesses and crashes on mv88e6xxx.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: rockchip: Fix PM usage reference of rockchip_i2s_tdm_resume
pm_runtime_get_sync will increment pm usage counter
even it failed. Forgetting to putting operation will
result in reference leak here. We fix it by replacing
it with pm_runtime_resume_and_get to keep usage counter
balanced.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
misc: fastrpc: fix list iterator in fastrpc_req_mem_unmap_impl
This is another instance of incorrect use of list iterator and
checking it for NULL.
The list iterator value 'map' will *always* be set and non-NULL
by list_for_each_entry(), so it is incorrect to assume that the
iterator value will be NULL if the list is empty (in this case, the
check 'if (!map) {' will always be false and never exit as expected).
To fix the bug, use a new variable 'iter' as the list iterator,
while use the original variable 'map' as a dedicated pointer to
point to the found element.
Without this patch, Kernel crashes with below trace:
Unable to handle kernel access to user memory outside uaccess routines
at virtual address 0000ffff7fb03750

Summary
In the Linux kernel, the following vulnerability has been resolved:
macsec: sync features on RTM_NEWLINK
Syzkaller managed to lock the lower device via ETHTOOL_SFEATURES:
netdev_lock include/linux/netdevice.h:2761 [inline]
netdev_lock_ops include/net/netdev_lock.h:42 [inline]
netdev_sync_lower_features net/core/dev.c:10649 [inline]
__netdev_update_features+0xcb1/0x1be0 net/core/dev.c:10819
netdev_update_features+0x6d/0xe0 net/core/dev.c:10876
macsec_notify+0x2f5/0x660 drivers/net/macsec.c:4533
notifier_call_chain+0x1b3/0x3e0 kernel/notifier.c:85
call_netdevice_notifiers_extack net/core/dev.c:2267 [inline]
call_netdevice_notifiers net/core/dev.c:2281 [inline]
netdev_features_change+0x85/0xc0 net/core/dev.c:1570
__dev_ethtool net/ethtool/ioctl.c:3469 [inline]
dev_ethtool+0x1536/0x19b0 net/ethtool/ioctl.c:3502
dev_ioctl+0x392/0x1150 net/core/dev_ioctl.c:759
It happens because lower features are out of sync with the upper:
__dev_ethtool (real_dev)
netdev_lock_ops(real_dev)
ETHTOOL_SFEATURES
__netdev_features_change
netdev_sync_upper_features
disable LRO on the lower
if (old_features != dev->features)
netdev_features_change
fires NETDEV_FEAT_CHANGE
macsec_notify
NETDEV_FEAT_CHANGE
netdev_update_features (for each macsec dev)
netdev_sync_lower_features
if (upper_features != lower_features)
netdev_lock_ops(lower) # lower == real_dev
stuck
...
netdev_unlock_ops(real_dev)
Per commit af5f54b0ef9e ("net: Lock lower level devices when updating
features"), we elide the lock/unlock when the upper and lower features
are synced. Makes sure the lower (real_dev) has proper features after
the macsec link has been created. This makes sure we never hit the
situation where we need to sync upper flags to the lower.

CVE-2022-49286 (GCVE-0-2022-49286)
Vulnerability from cvelistv5 – Published: 2025-02-26 01:56 – Updated: 2025-05-04 08:34

Summary
In the Linux kernel, the following vulnerability has been resolved:
tpm: use try_get_ops() in tpm-space.c
As part of the series conversion to remove nested TPM operations:
https://lore.kernel.org/all/20190205224723.19671-1-jarkko.sakkinen@linux.intel.com/
exposure of the chip->tpm_mutex was removed from much of the upper
level code. In this conversion, tpm2_del_space() was missed. This
didn't matter much because it's usually called closely after a
converted operation, so there's only a very tiny race window where the
chip can be removed before the space flushing is done which causes a
NULL deref on the mutex. However, there are reports of this window
being hit in practice, so fix this by converting tpm2_del_space() to
use tpm_try_get_ops(), which performs all the teardown checks before
acquring the mutex.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: oss: Fix PCM OSS buffer allocation overflow
We've got syzbot reports hitting INT_MAX overflow at vmalloc()
allocation that is called from snd_pcm_plug_alloc(). Although we
apply the restrictions to input parameters, it's based only on the
hw_params of the underlying PCM device. Since the PCM OSS layer
allocates a temporary buffer for the data conversion, the size may
become unexpectedly large when more channels or higher rates is given;
in the reported case, it went over INT_MAX, hence it hits WARN_ON().
This patch is an attempt to avoid such an overflow and an allocation
for too large buffers. First off, it adds the limit of 1MB as the
upper bound for period bytes. This must be large enough for all use
cases, and we really don't want to handle a larger temporary buffer
than this size. The size check is performed at two places, where the
original period bytes is calculated and where the plugin buffer size
is calculated.
In addition, the driver uses array_size() and array3_size() for
multiplications to catch overflows for the converted period size and
buffer bytes.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: idxd: Remove improper idxd_free
The call to idxd_free() introduces a duplicate put_device() leading to a
reference count underflow:
refcount_t: underflow; use-after-free.
WARNING: CPU: 15 PID: 4428 at lib/refcount.c:28 refcount_warn_saturate+0xbe/0x110
...
Call Trace:
<TASK>

entry_SYSCALL_64_after_hwframe+0x76/0x7e
The idxd_unregister_devices() which is invoked at the very beginning of
idxd_remove(), already takes care of the necessary put_device() through the
following call path:
idxd_unregister_devices() -> device_unregister() -> put_device()
In addition, when CONFIG_DEBUG_KOBJECT_RELEASE is enabled, put_device() may
trigger asynchronous cleanup via schedule_delayed_work(). If idxd_free() is
called immediately after, it can result in a use-after-free.
Remove the improper idxd_free() to avoid both the refcount underflow and
potential memory corruption during module unload.

Summary
In the Linux kernel, the following vulnerability has been resolved:
kernfs: Fix UAF in polling when open file is released
A use-after-free (UAF) vulnerability was identified in the PSI (Pressure
Stall Information) monitoring mechanism:
BUG: KASAN: slab-use-after-free in psi_trigger_poll+0x3c/0x140
Read of size 8 at addr ffff3de3d50bd308 by task systemd/1
psi_trigger_poll+0x3c/0x140

cgroup_file_show+0x150/0x268
cgroup_pressure_write+0x1dc/0x340
cgroup_file_write+0x274/0x548
Reproduction Steps:
1. Open test/cpu.pressure and establish epoll monitoring
2. Disable monitoring: echo 0 > test/cgroup.pressure
3. Re-enable monitoring: echo 1 > test/cgroup.pressure
The race condition occurs because:
1. When cgroup.pressure is disabled (echo 0 > cgroup.pressure), it:
- Releases PSI triggers via cgroup_file_release()
- Frees of->priv through kernfs_drain_open_files()
2. While epoll still holds reference to the file and continues polling
3. Re-enabling (echo 1 > cgroup.pressure) accesses freed of->priv
epolling disable/enable cgroup.pressure
fd=open(cpu.pressure)
while(1)
...
epoll_wait
kernfs_fop_poll
kernfs_get_active = true echo 0 > cgroup.pressure
... cgroup_file_show
kernfs_show
// inactive kn
kernfs_drain_open_files
cft->release(of);
kfree(ctx);
...
kernfs_get_active = false
echo 1 > cgroup.pressure
kernfs_show
kernfs_activate_one(kn);
kernfs_fop_poll
kernfs_get_active = true
cgroup_file_poll
psi_trigger_poll
// UAF
...
end: close(fd)
To address this issue, introduce kernfs_get_active_of() for kernfs open
files to obtain active references. This function will fail if the open file
has been released. Replace kernfs_get_active() with kernfs_get_active_of()
to prevent further operations on released file descriptors.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/page_owner: use strscpy() instead of strlcpy()
current->comm[] is not a string (no guarantee for a zero byte in it).
strlcpy(s1, s2, l) is calling strlen(s2), potentially
causing out-of-bound access, as reported by syzbot:
detected buffer overflow in __fortify_strlen

CVE-2025-39877 (GCVE-0-2025-39877)
Vulnerability from cvelistv5 – Published: 2025-09-23 06:00 – Updated: 2025-11-03 17:44

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/damon/sysfs: fix use-after-free in state_show()
state_show() reads kdamond->damon_ctx without holding damon_sysfs_lock.
This allows a use-after-free race:
CPU 0 CPU 1
----- -----
state_show() damon_sysfs_turn_damon_on()
ctx = kdamond->damon_ctx; mutex_lock(&damon_sysfs_lock);
damon_destroy_ctx(kdamond->damon_ctx);
kdamond->damon_ctx = NULL;
mutex_unlock(&damon_sysfs_lock);
damon_is_running(ctx); /* ctx is freed */
mutex_lock(&ctx->kdamond_lock); /* UAF */
(The race can also occur with damon_sysfs_kdamonds_rm_dirs() and
damon_sysfs_kdamond_release(), which free or replace the context under
damon_sysfs_lock.)
Fix by taking damon_sysfs_lock before dereferencing the context, mirroring
the locking used in pid_show().
The bug has existed since state_show() first accessed kdamond->damon_ctx.
Severity ?
No CVSS data available.

The root cause of this issue is we destory inline data until call
ext4_writepages under delay allocation mode. But there maybe already
convert from inline to extent. To solve this issue, we call
filemap_flush first..

Summary
In the Linux kernel, the following vulnerability has been resolved:
phy: qcom-qmp: fix reset-controller leak on probe errors
Make sure to release the lane reset controller in case of a late probe
error (e.g. probe deferral).
Note that due to the reset controller being defined in devicetree in
"lane" child nodes, devm_reset_control_get_exclusive() cannot be used
directly.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: firewire-lib: fix uninitialized flag for AV/C deferred transaction
AV/C deferred transaction was supported at a commit 00a7bb81c20f ("ALSA:
firewire-lib: Add support for deferred transaction") while 'deferrable'
flag can be uninitialized for non-control/notify AV/C transactions.
UBSAN reports it:

This commit fixes the bug. The bug has no disadvantage for the non-
control/notify AV/C transactions since the flag has an effect for AV/C
response with INTERIM (0x0f) status which is not used for the transactions
in AV/C general specification.

Summary
In the Linux kernel, the following vulnerability has been resolved:
watch_queue: Fix NULL dereference in error cleanup
In watch_queue_set_size(), the error cleanup code doesn't take account of
the fact that __free_page() can't handle a NULL pointer when trying to free
up buffer pages that did get allocated.
Fix this by only calling __free_page() on the pages actually allocated.
Without the fix, this can lead to something like the following:
BUG: KASAN: null-ptr-deref in __free_pages+0x1f/0x1b0 mm/page_alloc.c:5473
