The impacted element is the function QMatrix::make_sequential of the file exllamav2/exllamav2_ext/cuda/q_matrix.cu of the component GPTQ Index Handler. Executing a manipulation of the argument g_idx can lead to out-of-bounds write. The attack needs to be launched locally. The project was informed of the problem early through an issue report but has not responded yet.","state":0,"publishedAt":"2026-10-26T20:15:07.238+00:00","modifiedAt":"2026-10-26T20:15:07.238+00:00","affected":[{"ecosystem":"Vendor product","name":"ExLlamaV2","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"turboderp-org\",\n                    \"product\": \"ExLlamaV2\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0.3.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.3.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0.3.2\",\n                            \"status\": \"affected\"\n                        }\n                    ],\n                    \"cpes\": [\n                        \"cpe:2.3:a:turboderp-org:exllamav2:*:*:*:*:*:*:*:*\"\n                    ],\n                    \"modules\": [\n                        \"GPTQ Index Handler\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:X","score":4.8,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L/E:X/RL:X/RC:C","score":4.4,"severity":"MEDIUM"},{"system":"CVSS 3.0","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L/E:X/RL:X/RC:C","score":4.4,"severity":"MEDIUM"},{"system":"CVSS 2.0","vector":"AV:L/AC:L/Au:S/C:N/I:P/A:P/E:ND/RL:ND/RC:C","score":3.2,"severity":null}],"references":["https://vuldb.com/vuln/426401","https://vuldb.com/vuln/426401/cti","https://vuldb.com/cve/CVE-2026-116502","https://vuldb.com/submit/1022425","https://github.com/turboderp-org/exllamav2/issues/817","https://github.com/turboderp-org/exllamav2/"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-116502","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-116502","identifiers":["CVE-2026-116502"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
