This is caused by improperly using sg_init_one()\nwith vmalloc'd stack buffers (plain_key_blob).\n\nFix this by always using kmalloc() for buffers we give to the DCP crypto\ndriver.","published":"2025-02-27T03:15:12.000Z","lastModified":"2026-08-04T11:22:37.000Z","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":[],"affected":["linux/linux kernel"],"epss":{"score":0.00131,"percentile":0.02708,"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 (0.13%).
