A malicious model can force the code to read and invoke an out‑of‑range function pointer, resulting in a reproducible crash. Under specific conditions involving certain host memory layouts, it may be possible for an attacker to exploit this vulnerability to achieve controlled indirect kernel dispatch during model load.","published":"2026-10-12T17:17:36.000Z","lastModified":"2026-10-19T12:17:11.000Z","status":"Awaiting Analysis","sourceIdentifier":"cret@cert.org","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-20","CWE-125","CWE-787"],"affected":[],"epss":{"score":0.00589,"percentile":0.47895,"date":"2026-10-26","history":[{"date":"2026-10-13","score":0.00204,"percentile":0.09612}]},"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 (0.59%).
