CVE-2026-7450: PAR File Parsing NULL Pointer Dereference in Autodesk 3ds Max

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.

Security readout for executives and security teams

Plain-English summary

A crafted PAR file can crash Autodesk 3ds Max 2026 or 2027 when opened. The known impact is denial of service to the application, not data theft or code execution. Business urgency is moderate for teams that exchange or render third-party 3D content.

Executive priority

Prioritize during normal patch cycles unless 3ds Max is business-critical or handles frequent external assets. The issue can disrupt production work but sources indicate availability impact only.

Technical view

CVE-2026-7450 is a CWE-476 NULL pointer dereference in Autodesk 3ds Max PAR file parsing. CVSS 3.1 is 5.5: local attack vector, low complexity, no privileges, user interaction required, unchanged scope, and high availability impact only.

Likely exposure

Exposure is likely limited to workstations running Autodesk 3ds Max 2026 or 2027, especially where users open PAR files from clients, vendors, marketplaces, or shared project archives.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation. Exploitation requires a malicious PAR file to be parsed by 3ds Max, causing an application crash and denial of service.

Researcher notes

Affected products are Autodesk 3ds Max 2026 and 2027. Default status is otherwise unaffected in the source bundle. No exploit code, weaponization detail, fixed build number, or confirmed exploitation is provided.

Mitigation direction

  • Review Autodesk advisory ADSK-SA-2026-0006 and deploy the listed 3ds Max updates.
  • Use Autodesk Access or approved software management to distribute available fixes.
  • Restrict opening PAR files from untrusted or unsolicited sources.
  • Route third-party 3D assets through normal intake and scanning workflows.
  • Monitor Autodesk guidance for fixed build details if not already documented internally.

Validation and detection

  • Inventory endpoints for Autodesk 3ds Max 2026 and 2027 installations.
  • Confirm each affected installation has the advisory-recommended update applied.
  • Check asset intake workflows for controls around untrusted PAR files.
  • Review crash telemetry or helpdesk tickets for repeated 3ds Max PAR parsing crashes.
