CVE-2026-75148: Jkuhlmann Cgltf

Medium severity, CVSS 6.1. EPSS: 0.2% chance of exploitation in the next 30 days.

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.
