CVE-2026-64117

CVE-2026-64117 describes a Linux kernel issue in wifi/mac80211 where fast-RX rate capture uses the same skb->cb storage as IEEE80211_TX_INFO used by mesh paths. In the unicast forward path, rx/mesh code reuses the same skb and can either enqueue for TX or free the skb before RX_QUEUED handles ...

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-2026-46152

CVE-2026-46152 affects the Linux kernel’s wifi/mac80211 subsystem. The root cause is that ieee80211_invoke_fast_rx() uses a static per-invocation rx_result, causing concurrent callers to share a single instance and potentially overwrite results between ieee80211_rx_mesh_data() and the switch on r...
