CVE-2026-68414

CVE-2026-68414 affects the Linux kernel cfg80211 Wi‑Fi subsystem. When unregistering a wiphy, a queued or running cfg80211_sched_scan_results_wk can reference freed rdev state because sched_scan_res_wk is not drained during unregister. This allows a use-after-free scenario as the worker crosses t...
