CVE-2022-49646
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.
Does this matter?
Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.
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.
