CVE-2026-10200
Description
A flaw was found in Assimp. A local attacker could trigger a heap-based buffer overflow in the glTFCommon::CopyValue function, part of the 4x4 Matrix Parser component. This vulnerability could lead to limited information disclosure, denial of service, or other impacts on system integrity and availability.
Statement
This Moderate-severity heap-based buffer overflow in Assimp's glTFCommon::CopyValue function allows a local attacker to cause information disclosure, denial of service, or other impacts by manipulating 4x4 matrix parsing. Exploitation requires local access to the system.
Mitigation
To mitigate this issue, users should avoid processing untrusted 3D model files with applications that utilize the Assimp library. Restricting local user access to systems where Assimp is used to process potentially untrusted data can also reduce the attack surface.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
