5.9 (Medium) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N
Details

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath12k: fix dfs-radar and temperature event locking

The ath12k active pdevs are protected by RCU but the DFS-radar and temperature event handling code calling ath12k_mac_get_ar_by_pdev_id() was not marked as a read-side critical section.

Mark the code in question as RCU read-side critical sections to avoid any potential use-after-free issues.

Note that the temperature event handler looks like a place holder currently but would still trigger an RCU lockdep splat.

Compile tested only.
