The Centos security team deemed this advisory irrelevant for Centos:8.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-headers package and not the kernel-headers package as distributed by Centos.
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 ath11k_mac_get_arvif_by_vdev_id() 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.
