{"id":"UBUNTU-CVE-2024-58400","details":"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.","modified":"2026-10-28T20:15:31.475445897Z","published":"2026-10-27T01:19:00Z","upstream":["CVE-2024-58400"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-58400"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-58400"},{"type":"REPORT","url":"https://github.com/cveproject/cvelistv5/tree/main/cves/2024/58xxx/cve-2024-58400.json"},{"type":"REPORT","url":"https://github.com/ggml-org/llama.cpp/blob/b3681/examples/server/server.cpp#l789"},{"type":"REPORT","url":"https://github.com/ggml-org/llama.cpp/commit/eae597182cb61bbde0b26e7cec5999d28b9327fe"},{"type":"REPORT","url":"https://github.com/ggml-org/llama.cpp/commit/faf69d4237c9ae4d7f572b4674d1002463e8acd3"},{"type":"REPORT","url":"https://github.com/ggml-org/llama.cpp/pull/9359"},{"type":"REPORT","url":"https://github.com/ggml-org/llama.cpp/releases/tag/b3701"},{"type":"REPORT","url":"https://nvd.nist.gov/vuln/detail/cve-2024-58400"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/llama-cpp-before-b3701-out-of-bounds-read-in-llama-decode-via-token-ids"}],"affected":[{"package":{"name":"llama.cpp","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/llama.cpp?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8681+dfsg-1","9721+dfsg-1ubuntu1","10438+dfsg-1","10438+dfsg-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"libllama0","binary_version":"10438+dfsg-1ubuntu1"},{"binary_name":"llama.cpp","binary_version":"10438+dfsg-1ubuntu1"},{"binary_name":"llama.cpp-examples","binary_version":"10438+dfsg-1ubuntu1"},{"binary_name":"llama.cpp-services","binary_version":"10438+dfsg-1ubuntu1"},{"binary_version":"10438+dfsg-1ubuntu1","binary_name":"llama.cpp-tests"},{"binary_version":"10438+dfsg-1ubuntu1","binary_name":"llama.cpp-tools"},{"binary_version":"10438+dfsg-1ubuntu1","binary_name":"llama.cpp-tools-extra"},{"binary_version":"10438+dfsg-1ubuntu1","binary_name":"python3-gguf"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-58400.json"}},{"package":{"name":"llama.cpp","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/llama.cpp?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5882+dfsg-2","8064+dfsg-1ubuntu1","8681+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libllama0","binary_version":"8681+dfsg-1"},{"binary_name":"llama.cpp","binary_version":"8681+dfsg-1"},{"binary_name":"llama.cpp-examples","binary_version":"8681+dfsg-1"},{"binary_name":"llama.cpp-tests","binary_version":"8681+dfsg-1"},{"binary_version":"8681+dfsg-1","binary_name":"llama.cpp-tools"},{"binary_name":"llama.cpp-tools-extra","binary_version":"8681+dfsg-1"},{"binary_name":"python3-gguf","binary_version":"8681+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-58400.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H"},{"type":"CVSS_V4","score":"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"},{"type":"CVSS_V4","score":"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"},{"type":"Ubuntu","score":"medium"}]}
