A malicious model can force the code to read and invoke an out\u2011of\u2011range 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.\nhttps://www.cve.org/CVERecord?id=CVE-2026-84286https://kb.cert.org/vuls/id/369611https://github.com/turboderp-org/exllamav3/pull/310#cert #Turboderp-org #ExLlamaV3#CVE_2026_84286#bot", "creation_timestamp": "2026-10-12T18:17:09.395614Z"}]}
