Overview

CVE-2026-75148 is a medium-severity vulnerability. It was published on August 19, 2026 and has a CVSS 3.1 base score of 6.1 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 6.1, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
