CVE-2025-38643

CVE-2025-38643 affects the Linux kernel wifi stack (cfg80211). The root cause is a missing lock in cfg80211_check_and_end_cac(), while callers of wdev_chandef() are expected to hold the wiphy mutex; however the worker cfg80211_propagate_cac_done_wk() does not acquire it. This can trigger a warnin...
