Upgrade SLES:15.6 cluster-md-kmp-default to version 6.4.0-150600.23.14.2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream cluster-md-kmp-default package and not the cluster-md-kmp-default 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.
