{"id":"AZL-101174","summary":"CVE-2026-89892 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: em28xx: defer audio-only extension registration\n\nThe audio-only path registers extensions while probing the primary device.\nFor a dual-TS board, this happens before dev_next is created. The duplicate\ndevice inherits is_audio_only and is then independently inserted into\nem28xx_devlist.\n\nThe list is intended to contain only primary devices: extension operations\nreach the secondary device through dev_next. The independently linked\nsecondary can be freed during disconnect while its list node remains\nreachable, resulting in a use-after-free.\n\nDefer audio-only extension registration to the module-request work item. It\nruns only after probing has completed construction of the optional\nsecondary device, so only the primary is registered and extension callbacks\nreach the secondary through dev_next.","modified":"2026-09-18T05:37:08Z","published":"2026-09-16T11:16:57Z","upstream":["CVE-2026-89892"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89892"}],"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-101174.json"}}],"schema_version":"1.9.0"}
