| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: clear stale link mapping of ahvif->links_map
When an arvif is initialized in non-AP STA mode but MLO connection
preparation fails before the arvif is created
(arvif->is_created remains false), the error path attempts to delete all
links. However, link deletion only executes when arvif->is_created is true.
As a result, ahvif retains a stale entry of arvif that is initialized but
not created.
When a new arvif is initialized with the same link id, this stale mapping
triggers the following WARN_ON.

Fix this issue by unassigning the link vif and clearing ahvif->links_map
if arvif is only initialized but not created.

| In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: gfx3d: add parent to parent request map
After commit d228ece36345 ("clk: divider: remove round_rate() in favor
of determine_rate()") determining GFX3D clock rate crashes, because the
passed parent map doesn't provide the expected best_parent_hw clock
(with the roundd_rate path before the offending commit the
best_parent_hw was ignored).
Set the field in parent_req in addition to setting it in the req,
fixing the crash.

| In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: Recover from panthor_gpu_flush_caches() failures
We have seen a few cases where the whole memory subsystem is blocked
and flush operations never complete. When that happens, we want to:
- schedule a reset, so we can recover from this situation
- in the reset path, we need to reset the pending_reqs so we can send
new commands after the reset
- if more panthor_gpu_flush_caches() operations are queued after
the timeout, we skip them and return -EIO directly to avoid needless
waits (the memory block won't miraculously work again)
Note that we drop the WARN_ON()s because these hangs can be triggered
with buggy GPU jobs created by the UMD, and there's no way we can
prevent it. We do keep the error messages though.
v2:
- New patch
v3:
- Collect R-b
- Explicitly mention the fact we dropped the WARN_ON()s in the commit
message
v4:
- No changes |

AppArmor: Allow apparmor to handle unaligned dfa tables
The dfa tables can originate from kernel or userspace and 8-byte alignment
isn't always guaranteed and as such may trigger unaligned memory accesses
on various architectures. Resulting in the following

dmaengine: fsl-edma: don't explicitly disable clocks in .remove()
The clocks in fsl_edma_engine::muxclk are allocated and enabled with
devm_clk_get_enabled(), which automatically cleans these resources up,
but these clocks are also manually disabled in fsl_edma_remove(). This
causes warnings on driver removal for each clock:

procfs: fix missing RCU protection when reading real_parent in do_task_stat()
When reading /proc/[pid]/stat, do_task_stat() accesses task->real_parent
without proper RCU protection, which leads to:
cpu 0 cpu 1
----- -----
do_task_stat
var = task->real_parent
release_task
call_rcu(delayed_put_task_struct)
task_tgid_nr_ns(var)
rcu_read_lock <--- Too late to protect task->real_parent!
task_pid_ptr <--- UAF!
rcu_read_unlock
This patch uses task_ppid_nr_ns() instead of task_tgid_nr_ns() to add
proper RCU protection for accessing task->real_parent. |

p2pdma page from one to zero, however, in p2pmem_alloc_mmap() it uses
"VM_WARN_ON_ONCE_PAGE(!page_ref_count(page))" to assert the initial page
refcount should not be zero and the following will be reported when
CONFIG_DEBUG_VM is enabled:
