Application crash via unchecked texture-coordinate extraction
Published May 31, 2026 · Updated May 31, 2026
Null pointer dereference in Assimp 6.0.0 through 6.0.4 allows local users to crash importing applications via crafted glTF data. ImportMeshes ignores a false return from ExtractData for a texture-coordinate accessor, leaves the output pointer null, and then reads from that pointer. A local attacker must cause an Assimp consumer to load the malformed model; the demonstrated consequence is a process crash.
