Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: fix queue selection for mesh/OCB interfaces
When using iTXQ, the code assumes that there is only one vif queue for
broadcast packets, using the BE queue. Allowing non-BE queue marking
violates that assumption and txq->ac == skb_queue_mapping is no longer
guaranteed. This can cause issues with queue handling in the driver and
also causes issues with the recent ATF change, resulting in an AQL
underflow warning.
