{"id":"DEBIAN-CVE-2026-116816","details":"llama.cpp b5899 before b10261 contains a heap out-of-bounds write vulnerability in llm_tokenizer_plamo2::build that allows attackers to corrupt heap memory via crafted GGUF models. Attackers can supply BYTE-typed token text like \u003c0x-1\u003e whose negative parsed value writes token ids before the bytes_ buffer during model loading, causing crashes or potential code execution.","modified":"2026-10-27T18:00:08.248038202Z","published":"2026-10-27T01:19:06.437Z","upstream":["CVE-2026-116816"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-116816"}],"affected":[{"package":{"name":"llama.cpp","ecosystem":"Debian:14","purl":"pkg:deb/debian/llama.cpp?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10271+dfsg-1"}]}],"versions":["10108+dfsg-1","10108+dfsg1-1","10108+dfsg1-2","10192+dfsg-1","10192+dfsg-2","10192+dfsg-2~exp1","5151+dfsg-1~exp2","5151+dfsg-1~exp3","5318+dfsg-1","5318+dfsg-2","5713+dfsg-1","5760+dfsg-1","5760+dfsg-2","5760+dfsg-3","5760+dfsg-4","5882+dfsg-1","5882+dfsg-2","5882+dfsg-3","5882+dfsg-3~exp1","5882+dfsg-3~exp2","5882+dfsg-3~exp3","5882+dfsg-4","6641+dfsg-1","6641+dfsg-2","6641+dfsg-3","7593+dfsg-1","7593+dfsg-2","7593+dfsg-3","7965+dfsg-1","8064+dfsg-1","8064+dfsg-2","8461+dfsg-1","8611+dfsg-1","8681+dfsg-1","8870+dfsg-1","8941+dfsg-1","9009+dfsg-1","9071+dfsg-1","9190+dfsg-1","9413+dfsg-1","9555+dfsg-1","9601+dfsg-1","9721+dfsg-1","9895+dfsg-1","9895+dfsg-2","9895+dfsg-3","9951+dfsg-1","9951+dfsg-2","9951+dfsg-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-116816.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
