发布于3月6日3月6日 Members Ubuntu: (CVE-2023-52776): linux-nvidia-6.5 vulnerability Severity 4 CVSS (AV:L/AC:M/Au:N/C:P/I:P/A:P) Published 05/21/2024 Created 11/21/2024 Added 11/19/2024 Modified 11/19/2024 Description 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.
