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.

CVE-2023-53574 [MEDIUM] CWE-404 kernel: wifi: rtw88: delete timer and free skb queue when unloading
kernel: wifi: rtw88: delete timer and free skb queue when unloading
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.
Statement: The defect manifests only on driver unload/unbind: a pending TX-purge timer and non-purged queues could run after structures were freed, leading to UAF/crash.
This is a local, privileged issue (requires module unload or device unbind), so for the CVSS the PR:H.
