Attackers can craft GGUF files with enormous tensor extents that overflow ggml_nbytes() and strides, causing out-of-bounds memory access when buffers are sized from wrapped byte counts.","epss":{"date":"2026-11-02","percentile":0.02291,"score":0.00126},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://github.com/ggml-org/llama.cpp/issues/29383"}],"kev":null,"metrics":[{"score":6.9,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":6.6,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H","version":"3.1"}],"modifiedAt":1793645769937,"publishedAt":1793061239223,"references":[{"source":"CNA: VulnCheck","tags":["issue-tracking"],"url":"https://github.com/ggml-org/llama.cpp/issues/29383"},{"source":"CNA: VulnCheck","tags":["patch","issue-tracking"],"url":"https://github.com/ggml-org/llama.cpp/pull/29384"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/ggml-org/llama.cpp/commit/2149c00f4442dc59302e134a02e4c99d5f7ed9fc"},{"source":"CNA: VulnCheck","tags":["technical-description"],"url":"https://github.com/ggml-org/llama.cpp/blob/v0.5.0/ggml/src/gguf.cpp#L701"},{"source":"CNA: VulnCheck","tags":["release-notes"],"url":"https://github.com/ggml-org/llama.cpp/releases/tag/b11301"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/llama-cpp-b10398-before-b11301-integer-overflow-in-gguf-init-from-reader"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://github.com/ggml-org/llama.cpp/issues/29383"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
