This is a security hole. Fix it\nby clearing the s[12] array in thread_struct when fork.\n\nAs for kthread case, it's better to clear the s[12] array as well.","published":"2025-05-01T15:16:09.000Z","lastModified":"2026-06-17T05:19:19.000Z","status":"Analyzed","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H"},"cwe":[],"affected":["linux/linux kernel"],"epss":{"score":0.00208,"percentile":0.10767,"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":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.21%).
