With only a raw pointer and no structural\nreference, the mm_struct can be freed before the scheduler runs the job.\n\nFix this by calling mmgrab() to hold a structural mm_count reference for\nthe lifetime of the job, paired with mmdrop() in every cleanup path.","published":"2026-08-10T13:20:31.000Z","lastModified":"2026-08-17T06:17:46.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":[],"epss":{"score":0.00133,"percentile":0.0279,"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":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.13%).
