Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: mac80211: drop stray &amp;#39;static&amp;#39; from fast-RX rx_result<br /> <br /> ieee80211_invoke_fast_rx() is documented as safe for parallel RX, but<br /> its per-invocation rx_result is declared static. Concurrent callers then<br /> share one instance and can overwrite each other&amp;#39;s result between<br /> ieee80211_rx_mesh_data() and the switch on res.<br /> <br /> That can make a packet that was queued or consumed by<br /> ieee80211_rx_mesh_data() fall through into ieee80211_rx_8023(), or make<br /> a packet that should continue return as queued.<br /> <br /> Make res an automatic variable so each invocation keeps its own result.
