UBUNTU-CVE-2026-90375: High severity ubuntu/linux-hwe-edge vulnerability
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: fix non-AQL packet accounting for MLO stations mt76txqueueskb() overrides the wcid passed by the driver with sta->drvpriv, so the wcid might incorrectly be changed after TX, causing wcid->nonaqlpackets to be counted on the wrong wcid. For example, on the AP side, if a station's setup link is the 5G link and the station uses 2G to transmit a frame, the value of nonaqlpackets is increased on the 5G wcid but decreased on the 2G wcid. Once the inflated counter exceeds MTMAXNONAQLPKT, the TX scheduler permanently refuses to service the station. Drop the reassignment and account on the wcid used for transmission. This also records the actual wcid in the queue entry.
