In the Linux kernel, the following vulnerability has been resolved:

wifi: mac80211: reset state when starting AP fails

ieee80211_start_ap() can set enable_beacon (and beacon_int) and fail later, leaving it set forever. Scanning can then attempt to restore beaconing on such an interface, leading to:
