  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nwifi: mac80211: drop stray 'static' from fast-RX rx_result\nieee80211_invoke_fast_rx() is documented as safe for parallel RX, but\nits per-invocation rx_result is declared static. Concurrent callers then\nshare one instance and can overwrite each other's result between\nieee80211_rx_mesh_data() and the switch on res.\nThat can make a packet that was queued or consumed by\nieee80211_rx_mesh_data() fall through into ieee80211_rx_8023(), or make\na packet that should continue return as queued.\nMake res an automatic variable so each invocation keeps its own result.", "A flaw was found in the Linux kernel's Wi-Fi (mac80211) subsystem. The `ieee80211_invoke_fast_rx()` function uses a static variable for `rx_result`, 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 reported. Such issues can result in unexpected network behavior or a denial of service within the wireless communication." ],
