And it's required to release the resource using\nfree_resource().  Howerver, many people use kfree directly which will\nresult in kernel BUG.  In order to fix this without fixing every call\nsite, just leak a couple of bytes in such corner case.","published":"2025-02-26T07:00:56.000Z","lastModified":"2026-06-17T05:17:20.000Z","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":0.00266,"percentile":0.18316,"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 (0.27%).
