Summary
In the Linux kernel, the following vulnerability has been resolved:
net: hns3: fix oops when unload drivers paralleling
When unload hclge driver, it tries to disable sriov first for each
ae_dev node from hnae3_ae_dev_list. If user unloads hns3 driver at
the time, because it removes all the ae_dev nodes, and it may cause
oops.
But we can't simply use hnae3_common_lock for this. Because in the
process flow of pci_disable_sriov(), it will trigger the remove flow
of VF, which will also take hnae3_common_lock.
To fixes it, introduce a new mutex to protect the unload process.
Severity ?

Summary
In the Linux kernel, the following vulnerability has been resolved:
ptp: Ensure info->enable callback is always set
The ioctl and sysfs handlers unconditionally call the ->enable callback.
Not all drivers implement that callback, leading to NULL dereferences.
Example of affected drivers: ptp_s390.c, ptp_vclock.c and ptp_mock.c.
Instead use a dummy callback if no better was specified by the driver.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: ti: am65-cpsw: fix freeing IRQ in am65_cpsw_nuss_remove_tx_chns()
When getting the IRQ we use k3_udma_glue_tx_get_irq() which returns
negative error value on error. So not NULL check is not sufficient
to deteremine if IRQ is valid. Check that IRQ is greater then zero
to ensure it is valid.
There is no issue at probe time but at runtime user can invoke
.set_channels which results in the following call chain.
am65_cpsw_set_channels()
am65_cpsw_nuss_update_tx_rx_chns()
am65_cpsw_nuss_remove_tx_chns()
am65_cpsw_nuss_init_tx_chns()
At this point if am65_cpsw_nuss_init_tx_chns() fails due to
k3_udma_glue_tx_get_irq() then tx_chn->irq will be set to a
negative value.
Then, at subsequent .set_channels with higher channel count we
will attempt to free an invalid IRQ in am65_cpsw_nuss_remove_tx_chns()
leading to a kernel warning.
The issue is present in the original commit that introduced this driver,
although there, am65_cpsw_nuss_update_tx_rx_chns() existed as
am65_cpsw_nuss_update_tx_chns().

Summary
In the Linux kernel, the following vulnerability has been resolved:
batman-adv: Drop unmanaged ELP metric worker
The ELP worker needs to calculate new metric values for all neighbors
"reachable" over an interface. Some of the used metric sources require
locks which might need to sleep. This sleep is incompatible with the RCU
list iterator used for the recorded neighbors. The initial approach to work
around of this problem was to queue another work item per neighbor and then
run this in a new context.
Even when this solved the RCU vs might_sleep() conflict, it has a major
problems: Nothing was stopping the work item in case it is not needed
anymore - for example because one of the related interfaces was removed or
the batman-adv module was unloaded - resulting in potential invalid memory
accesses.
Directly canceling the metric worker also has various problems:
* cancel_work_sync for a to-be-deactivated interface is called with
rtnl_lock held. But the code in the ELP metric worker also tries to use
rtnl_lock() - which will never return in this case. This also means that
cancel_work_sync would never return because it is waiting for the worker
to finish.
* iterating over the neighbor list for the to-be-deactivated interface is
currently done using the RCU specific methods. Which means that it is
possible to miss items when iterating over it without the associated
spinlock - a behaviour which is acceptable for a periodic metric check
but not for a cleanup routine (which must "stop" all still running
workers)
The better approch is to get rid of the per interface neighbor metric
worker and handle everything in the interface worker. The original problems
are solved by:
* creating a list of neighbors which require new metric information inside
the RCU protected context, gathering the metric according to the new list
outside the RCU protected context
* only use rcu_trylock inside metric gathering code to avoid a deadlock
when the cancel_delayed_work_sync is called in the interface removal code
(which is called with the rtnl_lock held)

CVE-2025-21809 (GCVE-0-2025-21809)

Summary
In the Linux kernel, the following vulnerability has been resolved:
rxrpc, afs: Fix peer hash locking vs RCU callback
In its address list, afs now retains pointers to and refs on one or more
rxrpc_peer objects. The address list is freed under RCU and at this time,
it puts the refs on those peers.
Now, when an rxrpc_peer object runs out of refs, it gets removed from the
peer hash table and, for that, rxrpc has to take a spinlock. However, it
is now being called from afs's RCU cleanup, which takes place in BH
context - but it is just taking an ordinary spinlock.
The put may also be called from non-BH context, and so there exists the
possibility of deadlock if the BH-based RCU cleanup happens whilst the hash
spinlock is held. This led to the attached lockdep complaint.
Fix this by changing spinlocks of rxnet->peer_hash_lock back to
BH-disabling locks.

This led to the attached lockdep complaint.\n\nFix this by changing spinlocks of rxnet-\u003epeer_hash_lock back to\nBH-disabling locks.\n\n ================================\n WARNING: inconsistent lock state\n 6.13.0-rc5-build2+ #1223 Tainted: G E\n --------------------------------\n inconsistent {SOFTIRQ-ON-W} -\u003e {IN-SOFTIRQ-W} usage.\n swapper/1/0 [HC0[0]:SC1[1]:HE1:SE0] takes:\n ffff88810babe228 (\u0026rxnet-\u003epeer_hash_lock){+.?.}-{3:3}, at: rxrpc_put_peer+0xcb/0x180\n {SOFTIRQ-ON-W} state was registered at:\n mark_usage+0x164/0x180\n __lock_acquire+0x544/0x990\n lock_acquire.part.0+0x103/0x280\n _raw_spin_lock+0x2f/0x40\n rxrpc_peer_keepalive_worker+0x144/0x440\n process_one_work+0x486/0x7c0\n process_scheduled_works+0x73/0x90\n worker_thread+0x1c8/0x2a0\n kthread+0x19b/0x1b0\n ret_from_fork+0x24/0x40\n ret_from_fork_asm+0x1a/0x30\n irq event stamp: 972402\n hardirqs last enabled at (972402): [\u003cffffffff8244360e\u003e] _raw_spin_unlock_irqrestore+0x2e/0x50\n hardirqs last disabled at (972401): [\u003cffffffff82443328\u003e] _raw_spin_lock_irqsave+0x18/0x60\n softirqs last enabled at (972300): [\u003cffffffff810ffbbe\u003e] handle_softirqs+0x3ee/0x430\n softirqs last disabled at (972313): [\u003cffffffff810ffc54\u003e] __irq_exit_rcu+0x44/0x110\n\n other info that might help us debug this:\n Possible unsafe locking scenario:\n CPU0\n ----\n lock(\u0026rxnet-\u003epeer_hash_lock);\n \u003cInterrupt\u003e\n lock(\u0026rxnet-\u003epeer_hash_lock);\n\n *** DEADLOCK ***\n 1 lock held by swapper/1/0:\n #0: ffffffff83576be0 (rcu_callback){....}-{0:0}, at: rcu_lock_acquire+0x7/0x30\n\n stack backtrace:\n CPU: 1 UID: 0 PID: 0 Comm: swapper/1 Tainted: G E 6.13.0-rc5-build2+ #1223\n Tainted: [E]=UNSIGNED_MODULE\n Hardware name: ASUS All Series/H97-PLUS, BIOS 2306 10/09/2014\n Call Trace:\n \u003cIRQ\u003e\n dump_stack_lvl+0x57/0x80\n print_usage_bug.part.0+0x227/0x240\n valid_state+0x53/0x70\n mark_lock_irq+0xa5/0x2f0\n mark_lock+0xf7/0x170\n mark_usage+0xe1/0x180\n __lock_acquire+0x544/0x990\n lock_acquire.part.0+0x103/0x280\n _raw_spin_lock+0x2f/0x40\n rxrpc_put_peer+0xcb/0x180\n afs_free_addrlist+0x46/0x90 [kafs]\n rcu_do_batch+0x2d2/0x640\n rcu_core+0x2f7/0x350\n handle_softirqs+0x1ee/0x430\n __irq_exit_rcu+0x44/0x110\n irq_exit_rcu+0xa/0x30\n sysvec_apic_timer_interrupt+0x7f/0xa0\n \u003c/IRQ\u003e"

Summary
In the Linux kernel, the following vulnerability has been resolved:
timers/migration: Fix off-by-one root mis-connection
Before attaching a new root to the old root, the children counter of the
new root is checked to verify that only the upcoming CPU's top group have
been connected to it. However since the recently added commit b729cc1ec21a
("timers/migration: Fix another race between hotplug and idle entry/exit")
this check is not valid anymore because the old root is pre-accounted
as a child to the new root. Therefore after connecting the upcoming
CPU's top group to the new root, the children count to be expected must
be 2 and not 1 anymore.
This omission results in the old root to not be connected to the new
root. Then eventually the system may run with more than one top level,
which defeats the purpose of a single idle migrator.
Also the old root is pre-accounted but not connected upon the new root
creation. But it can be connected to the new root later on. Therefore
the old root may be accounted twice to the new root. The propagation of
such overcommit can end up creating a double final top-level root with a
groupmask incorrectly initialized. Although harmless given that the final
top level roots will never have a parent to walk up to, this oddity
opportunistically reported the core issue:
WARNING: CPU: 8 PID: 0 at kernel/time/timer_migration.c:543 tmigr_requires_handle_remote
CPU: 8 UID: 0 PID: 0 Comm: swapper/8
RIP: 0010:tmigr_requires_handle_remote
Call Trace:

? hrtimer_run_queues
update_process_times
tick_periodic
tick_handle_periodic
__sysvec_apic_timer_interrupt
sysvec_apic_timer_interrupt
</IRQ>
Fix the problem by taking the old root into account in the children count
of the new root so the connection is not omitted.
Also warn when more than one top level group exists to better detect
similar issues in the future.

Summary
In the Linux kernel, the following vulnerability has been resolved:
driver core: class: Fix wild pointer dereferences in API class_dev_iter_next()
There are a potential wild pointer dereferences issue regarding APIs
class_dev_iter_(init|next|exit)(), as explained by below typical usage:
// All members of @iter are wild pointers.
struct class_dev_iter iter;
// class_dev_iter_init(@iter, @class, ...) checks parameter @class for
// potential class_to_subsys() error, and it returns void type and does
// not initialize its output parameter @iter, so caller can not detect
// the error and continues to invoke class_dev_iter_next(@iter) even if
// @iter still contains wild pointers.
class_dev_iter_init(&iter, ...);
// Dereference these wild pointers in @iter here once suffer the error.
while (dev = class_dev_iter_next(&iter)) { ... };
// Also dereference these wild pointers here.
class_dev_iter_exit(&iter);
Actually, all callers of these APIs have such usage pattern in kernel tree.
Fix by:
- Initialize output parameter @iter by memset() in class_dev_iter_init()
and give callers prompt by pr_crit() for the error.
- Check if @iter is valid in class_dev_iter_next().

Summary
In the Linux kernel, the following vulnerability has been resolved:
rhashtable: Fix potential deadlock by moving schedule_work outside lock
Move the hash table growth check and work scheduling outside the
rht lock to prevent a possible circular locking dependency.
The original implementation could trigger a lockdep warning due to
a potential deadlock scenario involving nested locks between
rhashtable bucket, rq lock, and dsq lock. By relocating the
growth check and work scheduling after releasing the rth lock, we break
this potential deadlock chain.
This change expands the flexibility of rhashtable by removing
restrictive locking that previously limited its use in scheduler
and workqueue contexts.
Import to say that this calls rht_grow_above_75(), which reads from
struct rhashtable without holding the lock, if this is a problem, we can
move the check to the lock, and schedule the workqueue after the lock.
Modified so that atomic_inc is also moved outside of the bucket
lock along with the growth above 75% check.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: let net.core.dev_weight always be non-zero
The following problem was encountered during stability test:
(NULL net_device): NAPI poll function process_backlog+0x0/0x530 \
returned 1, exceeding its budget of 0.
------------[ cut here ]------------
list_add double add: new=ffff88905f746f48, prev=ffff88905f746f48, \
next=ffff88905f746e40.

The reproduction command is as follows:
sysctl -w net.core.dev_weight=0
ping 127.0.0.1
This is because when the napi's weight is set to 0, process_backlog() may
return 0 and clear the NAPI_STATE_SCHED bit of napi->state, causing this
napi to be re-polled in net_rx_action() until __do_softirq() times out.
Since the NAPI_STATE_SCHED bit has been cleared, napi_schedule_rps() can
be retriggered in enqueue_to_backlog(), causing this issue.
Making the napi's weight always non-zero solves this problem.
Triggering this issue requires system-wide admin (setting is
not namespaced).

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: mark GFP_NOIO around sysfs ->store()
sysfs ->store is called with queue freezed, meantime we have several
->store() callbacks(update_nr_requests, wbt, scheduler) to allocate
memory with GFP_KERNEL which may run into direct reclaim code path,
then potential deadlock can be caused.
Fix the issue by marking NOIO around sysfs ->store()
Severity ?
No CVSS data available.

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: protect access to buffers with no active references
nilfs_lookup_dirty_data_buffers(), which iterates through the buffers
attached to dirty data folios/pages, accesses the attached buffers without
locking the folios/pages.
For data cache, nilfs_clear_folio_dirty() may be called asynchronously
when the file system degenerates to read only, so
nilfs_lookup_dirty_data_buffers() still has the potential to cause use
after free issues when buffers lose the protection of their dirty state
midway due to this asynchronous clearing and are unintentionally freed by
try_to_free_buffers().
Eliminate this race issue by adjusting the lock section in this function.
Severity ?
7.8 (High)

CVE-2025-21804 (GCVE-0-2025-21804)

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: rcar-ep: Fix incorrect variable used when calling devm_request_mem_region()
The rcar_pcie_parse_outbound_ranges() uses the devm_request_mem_region()
macro to request a needed resource. A string variable that lives on the
stack is then used to store a dynamically computed resource name, which
is then passed on as one of the macro arguments. This can lead to
undefined behavior.
Depending on the current contents of the memory, the manifestations of
errors may vary. One possible output may be as follows:
$ cat /proc/iomem
30000000-37ffffff :
38000000-3fffffff :
Sometimes, garbage may appear after the colon.
In very rare cases, if no NULL-terminator is found in memory, the system
might crash because the string iterator will overrun which can lead to
access of unmapped memory above the stack.
Thus, fix this by replacing outbound_name with the name of the previously
requested resource. With the changes applied, the output will be as
follows:
$ cat /proc/iomem
30000000-37ffffff : memory2
38000000-3fffffff : memory3

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: xdp: Disallow attaching device-bound programs in generic mode
Device-bound programs are used to support RX metadata kfuncs. These
kfuncs are driver-specific and rely on the driver context to read the
metadata. This means they can't work in generic XDP mode. However, there
is no check to disallow such programs from being attached in generic
mode, in which case the metadata kfuncs will be called in an invalid
context, leading to crashes.
Fix this by adding a check to disallow attaching device-bound programs
in generic mode.
Severity ?

CVE-2025-21816 (GCVE-0-2025-21816)
Vulnerability from cvelistv5 – Published: 2025-02-27 20:04 – Updated: 2025-11-03 17:32

EPSS
Summary
In the Linux kernel, the following vulnerability has been resolved:
hrtimers: Force migrate away hrtimers queued after CPUHP_AP_HRTIMERS_DYING
hrtimers are migrated away from the dying CPU to any online target at
the CPUHP_AP_HRTIMERS_DYING stage in order not to delay bandwidth timers
handling tasks involved in the CPU hotplug forward progress.
However wakeups can still be performed by the outgoing CPU after
CPUHP_AP_HRTIMERS_DYING. Those can result again in bandwidth timers being
armed. Depending on several considerations (crystal ball power management
based election, earliest timer already enqueued, timer migration enabled or
not), the target may eventually be the current CPU even if offline. If that
happens, the timer is eventually ignored.
The most notable example is RCU which had to deal with each and every of
those wake-ups by deferring them to an online CPU, along with related
workarounds:
_ e787644caf76 (rcu: Defer RCU kthreads wakeup when CPU is dying)
_ 9139f93209d1 (rcu/nocb: Fix RT throttling hrtimer armed from offline CPU)
_ f7345ccc62a4 (rcu/nocb: Fix rcuog wake-up from offline softirq)
The problem isn't confined to RCU though as the stop machine kthread
(which runs CPUHP_AP_HRTIMERS_DYING) reports its completion at the end
of its work through cpu_stop_signal_done() and performs a wake up that
eventually arms the deadline server timer:
WARNING: CPU: 94 PID: 588 at kernel/time/hrtimer.c:1086 hrtimer_start_range_ns+0x289/0x2d0

dl_server_start

complete
cpu_stopper_thread
Instead of providing yet another bandaid to work around the situation, fix
it in the hrtimers infrastructure instead: always migrate away a timer to
an online target whenever it is enqueued from an offline CPU.
This will also allow to revert all the above RCU disgraceful hacks.

CVE-2025-21807 (GCVE-0-2025-21807)

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: fix queue freeze vs limits lock order in sysfs store methods
queue_attr_store() always freezes a device queue before calling the
attribute store operation. For attributes that control queue limits, the
store operation will also lock the queue limits with a call to
queue_limits_start_update(). However, some drivers (e.g. SCSI sd) may
need to issue commands to a device to obtain limit values from the
hardware with the queue limits locked. This creates a potential ABBA
deadlock situation if a user attempts to modify a limit (thus freezing
the device queue) while the device driver starts a revalidation of the
device queue limits.
Avoid such deadlock by not freezing the queue before calling the
->store_limit() method in struct queue_sysfs_entry and instead use the
queue_limits_commit_update_frozen helper to freeze the queue after taking
the limits lock.
This also removes taking the sysfs lock for the store_limit method as
it doesn't protect anything here, but creates even more nesting.
Hopefully it will go away from the actual sysfs methods entirely soon.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tty: xilinx_uartps: split sysrq handling
lockdep detects the following circular locking dependency:
CPU 0 CPU 1
========================== ============================
cdns_uart_isr() printk()
uart_port_lock(port) console_lock()
cdns_uart_console_write()
if (!port->sysrq)
uart_port_lock(port)
uart_handle_break()
port->sysrq = ...
uart_handle_sysrq_char()
printk()
console_lock()
The fixed commit attempts to avoid this situation by only taking the
port lock in cdns_uart_console_write if port->sysrq unset. However, if
(as shown above) cdns_uart_console_write runs before port->sysrq is set,
then it will try to take the port lock anyway. This may result in a
deadlock.
Fix this by splitting sysrq handling into two parts. We use the prepare
helper under the port lock and defer handling until we release the lock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
LoongArch: Fix warnings during S3 suspend
The enable_gpe_wakeup() function calls acpi_enable_all_wakeup_gpes(),
and the later one may call the preempt_schedule_common() function,
resulting in a thread switch and causing the CPU to be in an interrupt
enabled state after the enable_gpe_wakeup() function returns, leading
to the warnings as follow.

The root cause is acpi_enable_all_wakeup_gpes() uses a mutex to protect
acpi_hw_enable_all_wakeup_gpes(), and acpi_ut_acquire_mutex() may cause
a thread switch. Since there is no longer concurrent execution during
loongarch_acpi_suspend(), we can call acpi_hw_enable_all_wakeup_gpes()
directly in enable_gpe_wakeup().
The solution is similar to commit 22db06337f590d01 ("ACPI: sleep: Avoid
breaking S3 wakeup due to might_sleep()").

Summary
In the Linux kernel, the following vulnerability has been resolved:
ptp: vmclock: Set driver data before its usage
If vmclock_ptp_register() fails during probing, vmclock_remove() is
called to clean up the ptp clock and misc device.
It uses dev_get_drvdata() to access the vmclock state.
However the driver data is not yet set at this point.
Assign the driver data earlier.
Severity ?
No CVSS data available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
memory: tegra20-emc: fix an OF node reference bug in tegra_emc_find_node_by_ram_code()
As of_find_node_by_name() release the reference of the argument device
node, tegra_emc_find_node_by_ram_code() releases some device nodes while
still in use, resulting in possible UAFs. According to the bindings and
the in-tree DTS files, the "emc-tables" node is always device's child
node with the property "nvidia,use-ram-code", and the "lpddr2" node is a
child of the "emc-tables" node. Thus utilize the
for_each_child_of_node() macro and of_get_child_by_name() instead of
of_find_node_by_name() to simplify the code.
This bug was found by an experimental verification tool that I am
developing.
