In the Linux kernel, the following vulnerability has been resolved: wifi: b43: Stop/wake correct queue in DMA Tx path when QoS is disabled When QoS is disabled, the queue priority value will not map to the correct ieee80211 queue since there is only one queue. Stop/wake queue 0 when QoS is disabled to prevent trying to stop/wake a non-existent queue and failing to stop/wake the actual queue instantiated.
