In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
wifi: mt76: fix non-AQL packet accounting for MLO stations<\/p>\n
__mt76_tx_queue_skb() overrides the wcid passed by the driver with
\nsta->drv_priv, so the wcid might incorrectly be changed after TX,
\ncausing wcid->non_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.<\/p>\n
Drop the reassignment and account on the wcid used for transmission.
\nThis also records the actual wcid in the queue entry.<\/p>\n","protected":false},"excerpt":{"rendered":"
