Description OSIDB Bzimport 2025-10-04 16:02:35 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: rtw88: delete timer and free skb queue when unloading

Fix possible crash and memory leak on driver unload by deleting
TX purge timer and freeing C2H queue in 'rtw_core_deinit()',
shrink critical section in the latter by freeing COEX queue
out of TX report lock scope.
