This avoids issues like memory leaks when drivers are unbound\nwithout their devices being physically disconnected (e.g. on probe\ndeferral or configuration changes).\n\nFix the control message buffer lifetime so that it is released on driver\nunbind.","published":"2026-05-27T14:17:32.000Z","lastModified":"2026-06-25T21:18:31.000Z","status":"Analyzed","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":0.00114,"percentile":0.01482,"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 (0.11%).
