Application crash via unchecked node graph output
Published Aug 1, 2025 · Updated Aug 1, 2025
Null pointer dereference in MaterialXCore in MaterialX 1.39.2 allows attackers to crash applications via a crafted MTLX file. In getShaderNodes, nodeGraph->getOutput accepts an attacker-controlled output name and can return null, but the result enters the outputs vector and is dereferenced by output->getConnectedNode. The file must be parsed by an application using the affected MaterialXCore library, and exploitation terminates that process without reported data disclosure or modification.
