CVE-2023-52798

In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix dfs radar event locking The ath11k active pdevs are protected by RCU but the DFS radar event handling code calling ath11k_mac_get_ar_by_pdev_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.
