kernel: wifi: mac80211: drop stray 'static' from fast-RX rx_result

A flaw was found in the Linux kernel's Wi-Fi mac80211 subsystem. The ieee80211invokefastrx function uses a static variable for rxresult, which is shared across concurrent calls. This can lead to incorrect processing of Wi-Fi packets, where a packet might be mishandled or its status incorrectly...

kernel: wifi: mac80211: remove station if connection prep fails

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. When Multi-Link Operation MLO connection preparation fails, the system may not correctly remove the associated station. This can lead to a use-after-free or double-free vulnerability in the debugfs component, potentially causing...
