CVE-2025-53010 (GCVE-0-2025-53010)

Vulnerability from cvelistv5 – Published: 2025-08-01 17:58 – Updated: 2025-08-01 18:19

Title

MaterialX's unchecked nodeGraph->getOutput return is vulnerable to NULL Pointer Dereference

Summary

MaterialX is an open standard for the exchange of rich material and look-development content across applications and renderers. In version 1.39.2, when parsing shader nodes in a MTLX file, the MaterialXCore code accesses a potentially null pointer, which can lead to crashes with maliciously crafted files. An attacker could intentionally crash a target program that uses OpenEXR by sending a malicious MTLX file. This is fixed in version 1.39.3.

Severity

Summary

MaterialX Null Pointer Dereference in getShaderNodes due to Unchecked nodeGraph->getOutput return

Details

Summary

When parsing shader nodes in a MTLX file, the MaterialXCore code accesses a potentially null pointer, which can lead to crashes with maliciously crafted files.

Details

In src/MaterialXCore/Material.cpp, in function getShaderNodes, the following code fetches the output nodes for a given nodegraph input node:

// SNIP...
        else if (input->hasNodeGraphString())
        {
            // Check upstream nodegraph connected to the input.
            // If no explicit output name given then scan all outputs on the nodegraph.
            ElementPtr parent = materialNode->getParent();
            NodeGraphPtr nodeGraph = parent->getChildOfType<NodeGraph>(input->getNodeGraphString());
            if (!nodeGraph)
            {
                continue;
            }
            vector<OutputPtr> outputs;
            if (input->hasOutputString())
            {
                outputs.push_back(nodeGraph->getOutput(input->getOutputString())); // <--- null ptr is returned
            }
            else
            {
                outputs = nodeGraph->getOutputs();
            }
            for (OutputPtr output : outputs)
            {
                NodePtr upstreamNode = output->getConnectedNode(); // <--- CRASHES HERE
                if (upstreamNode && !shaderNodeSet.count(upstreamNode))
                {
                    if (!target.empty() && !upstreamNode->getNodeDef(target))
                    {
                        continue;
                    }
                    shaderNodeVec.push_back(upstreamNode);
                    shaderNodeSet.insert(upstreamNode);
                }
            }
        }
    }
// SNIP...

The issues arise because the nodeGraph->getOutput(input->getOutputString()) call can return a null pointer, therefore when trying to call output->getConnectedNode(), this results in a crash .

PoC

Please download nullptr_getshadernodes.mltx from the following link:

https://github.com/ShielderSec/poc/tree/main/CVE-2025-53010

build/bin/MaterialXView --material nullptr_getshadernodes.mtlx

Impact

An attacker could intentionally crash a target program that uses OpenEXR by sending a malicious MTLX file.

Severity

2.0 (Low)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
