How to fix?

Upgrade SLES:15.6 kernel-default-base to version 6.4.0-150600.23.14.2.150600.12.4.3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-default-base package and not the kernel-default-base package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

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.
