CVE-2026-98334

A vulnerability exists in the Linux kernel 's mac80211 WiFi subsystem where the ieee80211_start_ap() function can set enable_beacon and beacon_int but fail to reset them upon an error. This persistent state can cause a divide error (Oops) in hwsim when scanning attempts to restore beaconing. Addi...

EUVD-2026-93319

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: reset state when starting AP fails ieee80211startap can set enablebeacon and beaconint and fail later, leaving it set forever. Scanning can then attempt to restore beaconing on such an interface, leading to: Oops:...
