In this particular case Smack sees a mount option\nthat it recognizes, and returns 0. A call to a BPF hook follows, which\nreturns -ENOPARAM, which confuses the caller because Smack has processed\nits data.\n\nThe SELinux hook incorrectly returns 1 on success. There was a time\nwhen this was correct, however the current expectation is that it\nreturn 0 on success. This is repaired.","published":"2025-02-26T07:00:55.000Z","lastModified":"2026-06-17T05:17:18.000Z","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":[],"affected":["linux/linux kernel"],"epss":{"score":0.00269,"percentile":0.18959,"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%).
