CVE-2023-52776 is fixed in 22 products on 1 platform, first by DEBIAN-CVE-2023-52776, released May 21, 2024. It is not reported as exploited. Patch Radar priority: High. - Web page: https://patchblox.com/security/cve/CVE-2023-52776 - Priority: High - CVSS: 8.8 (high) - EPSS: 0.0086 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: May 21, 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. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | dtb-aarch64 opensuse-leap 15.6 | 6.4.0-150600.23.14.1 |
