CVE-2026-0538
📋 TL;DR
A malicious GIF file can trigger an out-of-bounds write vulnerability in Autodesk 3ds Max, allowing attackers to execute arbitrary code with the privileges of the current user. This affects all users who open untrusted GIF files in vulnerable versions of 3ds Max.
💻 Affected Systems
- Autodesk 3ds Max
📦 What is this software?
3ds Max by Autodesk
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through remote code execution, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Local privilege escalation or arbitrary code execution when a user opens a malicious GIF file, potentially leading to malware installation or data exfiltration.
If Mitigated
Limited impact with proper application sandboxing and user privilege restrictions, though file processing could still crash.
🎯 Exploit Status
Exploitation requires user interaction to open a malicious file. No public exploit code is currently available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2026.2 or later
Vendor Advisory: https://www.autodesk.com/trust/security-advisories/adsk-sa-2026-0002
Restart Required: Yes
Instructions:
1. Open Autodesk Access. 2. Check for updates. 3. Install version 2026.2 or later. 4. Restart 3ds Max.
🔧 Temporary Workarounds
Disable GIF file association
windowsPrevent 3ds Max from automatically opening GIF files by changing file associations in Windows.
Control Panel > Default Programs > Associate a file type or protocol with a program > Change .gif to open with a different application
Restrict file access
windowsUse application control policies to block execution of untrusted GIF files in 3ds Max.
🧯 If You Can't Patch
- Run 3ds Max with minimal user privileges to limit impact of potential code execution.
- Implement network segmentation to isolate 3ds Max systems from critical assets.
