CVE-2025-11274Public exploit

Process crash via unchecked material-count allocation

Published Oct 5, 2025 · Updated Feb 24, 2026

Resource exhaustion in Assimp 6.0.2's Q3D importer allows local users to crash a consuming process with a crafted Quick3D file. Q3DImporter::InternReadFile reads numMats directly from the file and passes it to materials.reserve and repeated emplace operations without validating the count. Exploitation requires a local user to make an Assimp-linked process parse the file; the reported consequence is process termination from an oversized allocation.
