  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: fix non-AQL packet accounting for MLO stations\n\n__mt76_tx_queue_skb() overrides the wcid passed by the driver with\nsta-\u003edrv_priv, so the wcid might incorrectly be changed after TX,\ncausing wcid-\u003enon_aql_packets to be counted on the wrong wcid. For\nexample, on the AP side, if a station's setup link is the 5G link and\nthe station uses 2G to transmit a frame, the value of non_aql_packets\nis increased on the 5G wcid but decreased on the 2G wcid. Once the\ninflated counter exceeds MT_MAX_NON_AQL_PKT, the TX scheduler\npermanently refuses to service the station.\n\nDrop the reassignment and account on the wcid used for transmission.\nThis also records the actual wcid in the queue entry.",
