Attackers can exploit this vulnerability to crash the server with SIGSEGV causing denial of service for all connected users, or corrupt token sampling probabilities by reading garbage values from memory before the allocated buffer.","state":0,"publishedAt":"2026-08-06T15:45:52.293+00:00","modifiedAt":"2026-10-29T21:15:40.528+00:00","affected":[{"ecosystem":"Vendor product","name":"llama.cpp","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"ggml-org\",\n                    \"product\": \"llama.cpp\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"b3978\",\n                            \"lessThanOrEqual\": \"b9058\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"defaultStatus\": \"affected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.5,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://github.com/Vladimir-tokarev-cyera/llama-cpp-security-patches","https://www.vulncheck.com/advisories/llama-cpp-b3978-b9058-integer-underflow-via-dry-sampler"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-43628","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-43628","identifiers":["CVE-2026-43628"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
