{"id":"CVE-2024-58400","aliases":[],"title":"llama.cpp before b3701 Out-of-Bounds Read in llama_decode via Token IDs","description":"llama.cpp before b3701 contains an out-of-bounds read vulnerability in llama_decode_internal and llama_encode_internal that allows remote unauthenticated attackers to read memory by supplying unvalidated token IDs. Attackers can send integer-array prompts to the llama-server /completion endpoint with IDs outside 0 to n_vocab to read embedding memory out of bounds or crash the process.","severity":"high","score":8.8,"published":"2026-10-27T00:33:57.354Z","modified":"2026-10-27T14:14:21.519Z","withdrawn":false,"knownExploited":false,"affected":[],"references":["https://github.com/ggml-org/llama.cpp/pull/9359","https://github.com/ggml-org/llama.cpp/commit/faf69d4237c9ae4d7f572b4674d1002463e8acd3","https://github.com/ggml-org/llama.cpp/commit/eae597182cb61bbde0b26e7cec5999d28b9327fe","https://github.com/ggml-org/llama.cpp/blob/b3681/examples/server/server.cpp#L789","https://github.com/ggml-org/llama.cpp/releases/tag/b3701","https://www.vulncheck.com/advisories/llama-cpp-before-b3701-out-of-bounds-read-in-llama-decode-via-token-ids"],"sources":[{"name":"CVE","id":"CVE-2024-58400","modified":"2026-10-27T14:14:21.519Z","url":"https://www.cve.org/CVERecord?id=CVE-2024-58400"}],"assessments":[{"source":"CNA","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.8},{"source":"CNA","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","score":8.2}]}
