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counts.","severity":"medium","score":6.9,"published":"2026-10-27T00:33:59.223Z","modified":"2026-10-27T00:33:59.223Z","withdrawn":false,"knownExploited":false,"affected":[],"references":["https://github.com/ggml-org/llama.cpp/issues/29383","https://github.com/ggml-org/llama.cpp/pull/29384","https://github.com/ggml-org/llama.cpp/commit/2149c00f4442dc59302e134a02e4c99d5f7ed9fc","https://github.com/ggml-org/llama.cpp/blob/v0.5.0/ggml/src/gguf.cpp#L701","https://github.com/ggml-org/llama.cpp/releases/tag/b11301","https://www.vulncheck.com/advisories/llama-cpp-b10398-before-b11301-integer-overflow-in-gguf-init-from-reader"],"sources":[{"name":"CVE","id":"CVE-2026-116829","modified":"2026-10-27T00:33:59.223Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-116829"}],"assessments":[{"source":"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","score":6.9},{"source":"VulnCheck","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H","score":6.6}],"sourceAffected":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T20:10:32.935Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
