In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: fix non-AQL packet accounting for MLO stations __mt76_tx_queue_skb() overrides the wcid passed by the driver with sta->drv_priv, so the wcid might incorrectly be changed after TX, causing wcid->non_aql_packets 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 non_aql_packets is increased on the 5G wcid but decreased on the 2G wcid. Once the inflated counter exceeds MT_MAX_NON_AQL_PKT, 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.
Fix
Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
