CVE-2025-53010
📋 TL;DR
MaterialX versions before 1.39.3 contain a null pointer dereference vulnerability when parsing malicious MTLX files. This allows attackers to crash applications using MaterialX for material processing, causing denial of service. Any software using vulnerable MaterialX libraries for parsing MTLX files is affected.
💻 Affected Systems
- MaterialX library
- Applications using MaterialX for material processing
- Renderers supporting MaterialX format
📦 What is this software?
Materialx by Linuxfoundation
⚠️ Risk & Real-World Impact
Worst Case
Complete application crash leading to denial of service, potentially disrupting rendering pipelines, visual effects workflows, or material processing systems.
Likely Case
Application crashes when processing malicious MTLX files, causing temporary service disruption until restart.
If Mitigated
No impact if patched version is used or if MTLX file processing is restricted to trusted sources.
🎯 Exploit Status
Proof of concept available on GitHub. Exploitation requires delivering a malicious MTLX file to vulnerable application.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.39.3
Vendor Advisory: https://github.com/AcademySoftwareFoundation/MaterialX/security/advisories/GHSA-3jhf-gxhr-q4cx
Restart Required: Yes
Instructions:
1. Update MaterialX library to version 1.39.3 or later. 2. Rebuild applications using MaterialX. 3. Restart affected services.
🔧 Temporary Workarounds
Restrict MTLX file sources
allOnly accept MTLX files from trusted sources and implement file validation
Input validation
allImplement strict validation of MTLX files before parsing
🧯 If You Can't Patch
- Implement strict file upload controls and only accept MTLX files from trusted sources
- Monitor for application crashes and implement automatic restart mechanisms
🔍 How to Verify
Check if Vulnerable:
Check MaterialX library version. If version < 1.39.3 and application parses MTLX files, it is vulnerable.Check Version:
Check MaterialX version in application dependencies or library filesVerify Fix Applied:
Verify MaterialX version is 1.39.3 or later and test with known malicious MTLX file to ensure no crash occurs.📡 Detection & Monitoring
Log Indicators:
- Application crashes when processing MTLX files
