CVE ID :CVE-2026-75148
Published : Aug. 19, 2026, 1:37 p.m. | 23 minutes ago
Description :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.
Severity: 6.9 | MEDIUM
