In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix gtk offload status event locking
The ath11k active pdevs are protected by RCU but the gtk offload status event handling code calling ath11kmacgetarvifbyvdevid() was not marked as a read-side critical section.
Mark the code in question as an RCU read-side critical section to avoid any potential use-after-free issues.
Compile tested only.
