CVE-2025-11797
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA maliciously crafted DWG file, when parsed through Autodesk 3ds Max, can force a Use-After-Free vulnerability. A malicious actor can leverage this vulnerability to cause a crash, read sensitive data, or execute arbitrary code in the context of the current process.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA Use-After-Free vulnerability exists in Autodesk 3ds Max when parsing maliciously crafted DWG files. The parser frees memory during processing but subsequently attempts to access that freed memory region, leading to memory corruption that can be leveraged for code execution or denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed 3ds Max versionOpen 3ds Max and go to Help > About Autodesk 3ds Max, or right-click the 3dsmax.exe file and select Properties > Details to view the Product versionAffected if The version listed is 2026, 2026.1, 2026.2, or any 2026.x version prior to 2026.3
-
Verify DWG import capability is presentAttempt to import a DWG file via File > Import or check if DWG/DXF import plugin is listed in 3ds Max plugin manager (Manage > Plugin Manager)Affected if DWG import functionality is available and enabled in the installation
-
Confirm DWG file parsing occurs in your workflowReview recent file access logs or check for .dwg files in recent project directories, or simply note whether you or your team open DWG files in 3ds MaxAffected if You process, open, or import DWG files using the affected 3ds Max version
-
Identify DWG-related modulesCheck the 3ds Max installation directory (typically Program Files/Autodesk/3ds Max 2026/bin) for DLLs related to DWG parsing, such as dwg*.dll or ADSK*.dll filesAffected if DWG parser DLLs are present in the 3ds Max bin directory
You are affected if your installed 3ds Max version is 2026 through 2026.2.x AND you import or process DWG files in your workflow.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2026.3
Apply the vendor-supplied patch from Autodesk. Until patched, exercise caution with DWG files from untrusted sources and consider using file quarantine procedures for external DWG files.
3ds Max 2026.3
- Back up all critical projects and files before updating
- Navigate to the official Autodesk website or your Autodesk Account portal
- Download Autodesk 3ds Max version 2026.3 or later
- Run the installer and follow Autodesk's standard installation prompts to complete the update
- Launch 3ds Max and verify the version displays as 2026.3 or higher
