Furthermore it's still\npossible that the caller has not yet called wait_for_completion,\nresulting in another potential UAF.\n\nFix this by making the caller use cancel_work_sync and then freeing\nthe memory safely.","published":"2024-07-10T08:15:11.000Z","lastModified":"2026-10-15T01:18:35.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-401"],"affected":["linux/linux kernel"],"epss":{"score":0.00239,"percentile":0.14839,"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":"low","text":"Lower severity and a low EPSS score (0.24%).
