{"id":"AZL-102968","summary":"CVE-2026-90116 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: mtpav: shut down output timer before card teardown\n\nsnd_mtpav_output_timer() rearms chip-\u003etimer while holding\nchip-\u003espinlock and accesses the card-private mtpav state.\n\nsnd_mtpav_free() currently takes the same lock and calls\ntimer_delete() when the timer is active. This only removes a\npending timer; it does not wait for a callback that is already\nrunning and does not prevent the callback from rearming the timer.\n\nA callback running on another CPU can therefore continue after\nsnd_mtpav_free() releases the lock and access the card-private\nstate while the card is being torn down. It can also rearm the\ntimer after timer_delete() has returned.\n\nCall timer_shutdown_sync() without holding chip-\u003espinlock. This\nwaits for any running callback to finish and prevents further\nrearming before the card-private mtpav state is released.","modified":"2026-09-19T05:33:49Z","published":"2026-09-17T17:17:03Z","upstream":["CVE-2026-90116"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90116"}],"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-102968.json"}}],"schema_version":"1.9.0"}
