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...

CVE-2026-63869

A flaw was found in the Linux kernel's mac80211 WiFi subsystem. This vulnerability allows an attacker to cause undefined behavior by injecting a specially crafted frame with an invalid radiotap header. This can lead to system instability or a denial of service DoS, potentially causing the system ...

CVE-2026-64030

A flaw was found in the Linux kernel's Wi-Fi mac80211 component. A connected WiFi 7 Access Point AP can trigger an out-of-bounds write by sending a specially crafted EPCS Enable Response action frame. This vulnerability can lead to a kernel crash, resulting in a Denial of Service DoS for the...

CVE-2026-64117

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. This use-after-free vulnerability arises from incorrect handling of fast-RX rate data during mesh processing. This can lead to memory corruption, which an attacker could potentially exploit to cause a system crash denial of service...
