CVE-2023-52777

CVE-2023-52777 affects the Linux kernel ath11k wifi driver. The gtk offload status event handler called ath11k_mac_get_arvif_by_vdev_id() was not in an RCU read-side critical section, risking use-after-free on active pdevs protected by RCU. The fix marks this code path as an RCU read-side critica...
