{"id":"AZL-102755","summary":"CVE-2026-90375 affecting package kernel 6.6.150.1-1","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.","modified":"2026-09-18T14:16:34.239328741Z","published":"2026-09-17T17:17:36Z","upstream":["CVE-2026-90375"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90375"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-102755.json"}}],"schema_version":"1.9.0"}
