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.","published":"2026-09-11T20:18:58.000Z","lastModified":"2026-10-19T09:17:25.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00173,"percentile":0.06639,"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.
