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. Log of issue before change (with
kernel parameter qos=0): [ +5.112651] ------------[ cut here ]------------
