Description

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

Affected configurations

• linux linux kernel (>= 6.4 < 6.6.140) • linux linux kernel (>= 6.7 < 6.12.88) • linux linux kernel (>= 6.13 < 6.18.30) • linux linux kernel (>= 6.19 < 7.0.7) • linux linux kernel 7.1
