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 · unedited
A maliciously crafted PAR file, when parsed through Autodesk 3ds Max, can force a NULL Pointer Dereference vulnerability. Successful exploitation may cause the application to crash, leading to a denial-of-service condition.

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 confidence

A NULL Pointer Dereference vulnerability exists in Autodesk 3ds Max when parsing maliciously crafted PAR (scene) files. During file parsing, the application attempts to dereference a NULL pointer without proper validation, causing an access violation and application crash.

MitigationApply vendor-supplied patch when available; in the interim, implement file type restrictions to block untrusted PAR files and educate users against opening files from untrusted sources.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check installed 3ds Max version
    Open 3ds Max and navigate to Help > About Autodesk 3ds Max, or right-click the 3ds Max executable and select Properties > Details to view the Product Version
    Affected if The displayed version is 2026 or 2027
  2. Confirm PAR file support is present
    Verify that the 3ds Max installation includes PAR (parameter) file import/export capabilities by checking if the File > Import menu lists PAR files or by searching for PAR-related plugins in the plugins folder
    Affected if PAR file parsing functionality exists in the installation
  3. Identify PAR file handling pathway
    Attempt to locate the PAR file importer module or check the application log for PAR-related loading messages when opening a sample PAR file
    Affected if The application loads and processes PAR files through its parsing pipeline
  4. Verify vulnerable code path is reachable
    Check if the PAR parser module (typically named something like parimporter.dli or parse.dlu) is loaded by the application - this can be confirmed by monitoring loaded modules or checking installation directories for PAR-related DLLs
    Affected if PAR parsing DLLs are present and loadable by the application

The environment is affected if Autodesk 3ds Max version 2026 or 2027 is installed and the application can parse PAR (parameter) files, as the NULL pointer dereference triggers during PAR file parsing operations.
