{"id":"CVE-2026-75148","summary":"cgltf 1.15 Integer Overflow via cgltf_validate() Accessor Bounds Check","details":"cgltf through 1.15 contains an integer overflow vulnerability in the non-sparse accessor bounds check within cgltf_validate() that allows remote attackers to cause memory disclosure and denial of service by supplying crafted accessor count values. Attackers can provide malformed .gltf or .glb input with a specially crafted accessor count to overflow the unsigned integer multiplication of accessor stride and element count, causing the bounds check to pass and triggering a heap out-of-bounds read when cgltf_accessor_read_float() is subsequently called on the validated malformed accessor.","modified":"2026-09-08T11:45:48.504154939Z","published":"2026-08-19T13:37:42.321Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/75xxx/CVE-2026-75148.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-190"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/75xxx/CVE-2026-75148.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-75148"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/cgltf-integer-overflow-via-cgltf-validate-accessor-bounds-check"},{"type":"REPORT","url":"https://github.com/jkuhlmann/cgltf/issues/301"},{"type":"PACKAGE","url":"https://github.com/jkuhlmann/cgltf"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/jkuhlmann/cgltf","events":[{"introduced":"0"},{"fixed":"360db1a95480fe102ae9c69b27c5d101167ff5ba"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"1.15"},{"fixed":"1.15"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["v1.14","v1.13","v1.12","v1.11","v1.10","v1.9","v1.8","v1.7","v1.6","v1.5","v1.4","v1.3","v1.2","v1.1","v1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-75148.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
