Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: ath12k: fix dfs-radar and temperature event locking<br /> <br /> The ath12k active pdevs are protected by RCU but the DFS-radar and<br /> temperature event handling code calling ath12k_mac_get_ar_by_pdev_id()<br /> was not marked as a read-side critical section.<br /> <br /> Mark the code in question as RCU read-side critical sections to avoid<br /> any potential use-after-free issues.<br /> <br /> Note that the temperature event handler looks like a place holder<br /> currently but would still trigger an RCU lockdep splat.<br /> <br /> Compile tested only.
