The firmware loader keeps the\ncallback module pinned and holds a device reference, but the callback\nstill uses driver-private HDA state.\n\nComponent unbind removes controls and DSP state immediately. Later\ndevice removal tears down the TAS2781 private data, including\ncodec_lock. If the async firmware callback runs after unbind has\nstarted, it can operate on state that is being torn down.\n\nCancel or synchronize the async firmware request before removing\ncontrols and DSP state. A queued callback is cancelled, and an\nalready-running callback is allowed to finish before unbind continues.","published":"2026-09-04T17:16:59.000Z","lastModified":"2026-09-04T17:16:59.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00206,"percentile":0.10613,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
