{"id":"AZL-100602","summary":"CVE-2026-80938 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7615: avoid waiting for mac work under the mt76 mutex\n\nmt7615_suspend() acquired the mt76 mutex and then called\ncancel_delayed_work_sync() on mac_work.  mt7615_mac_work() acquires the\nsame mutex via mt7615_mutex_acquire() at the top of the worker, so if\nmac_work is already running and blocked on the mutex, the suspend path\ndeadlocks waiting for the work it holds the mutex against.\n\nFlush scan_work and mac_work before taking the mutex, matching the\nsuspend paths in mt7921 and mt7925.  scan_work only takes the mt76\nspinlock, but moving it keeps the sequence consistent.  This also keeps\nmac_work from running over an already suspended HIF, which the previous\nsplit (async cancel under the lock, sync cancel after release) would\nhave allowed.","modified":"2026-09-13T06:06:36Z","published":"2026-09-11T20:18:58Z","upstream":["CVE-2026-80938"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80938"}],"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-100602.json"}}],"schema_version":"1.9.0"}
