GHSA-8998-MV35-8CJ9

Vulnerability from github – Published: 2025-10-23 12:31 – Updated: 2025-10-23 12:31

Details

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.

Severity

5.5 (Medium)
