This causes both a memory leak\nand a potential information leak.\n\nFix this by calling kfree_sensitive() on both password buffers before\nreturning in this error case.","published":"2026-01-23T15:16:06.000Z","lastModified":"2026-06-17T10:03:46.000Z","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:H/I:N/A:N"},"cwe":["CWE-401"],"affected":["linux/linux kernel"],"epss":{"score":0.00137,"percentile":0.0306,"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":"low","text":"Lower severity and a low EPSS score (0.14%).
