Those URBs\nself-resubmit, and their completion handlers reschedule the work.\n\nA URB that completes in the small window between cancel_work_sync() and\nusb_kill_anchored_urbs() therefore re-arms the work after its only\ncancel.  Nothing cancels it again before snd_card_free() frees the\ncard-private tascam structure, so the work handler then runs on freed\nmemory.\n\nKill the anchored URBs before cancelling the work; once the work is\ncancelled no remaining URB can complete to re-arm it.","published":"2026-07-25T10:17:35.000Z","lastModified":"2026-08-17T05:17:55.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00206,"percentile":0.1061,"date":"2026-10-26","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.
