CVE-2023-53229

Data corruption via invalid station-removal callback

Published Sep 15, 2025 · Updated Aug 5, 2026

Data corruption in Linux kernel mac80211 allows local users to interrupt service during removal of a non-uploaded wireless station. In __sta_info_destroy_part1, mac80211 called drv_sta_pre_rcu_remove when sta->uploaded was false, passing driver-private state that had never been initialized. Reachability requires local low-privileged access and a path that removes such a station; no data-reading or data-writing impact is reported.
