kernel: wifi: mac80211: Discard Beacon frames to non-broadcast address

A beacon protection bypass vulnerability was found in the Linux kernel's mac80211 WiFi stack. According to IEEE 802.11-2020, beacon frames must be sent to the broadcast address, but mac80211 incorrectly accepts unicast beacon frames with the Protected Frame bit set to 1. This allows attackers to...
