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 ath12kmacgetarbypdevid() 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.
