CVE-2026-0659
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 USD file, when loaded or imported into Autodesk Arnold or Autodesk 3ds Max, can force an Out-of-Bounds Write vulnerability. A malicious actor can leverage this vulnerability to 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 confidenceAn out-of-bounds write vulnerability exists in the USD file parser of Autodesk Arnold and 3ds Max. When loading or importing a maliciously crafted USD file, the software can be forced to write data beyond allocated buffer boundaries, enabling arbitrary code execution in the context of the current process.

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.
-
Identify installed Autodesk productCheck if Autodesk Arnold or 3ds Max is installed on the system. Look for the application in Program Files or verify via the software's About/Help menu to confirm the exact product name and version.Affected if Neither Arnold nor 3ds Max is installed, so the vulnerability does not apply.
-
Determine the product versionOpen Arnold or 3ds Max and navigate to Help > About or use the command line interface to retrieve the version number. Compare this against any known affected version ranges for your product.Affected if The installed version falls within an affected version range for Arnold or 3ds Max.
-
Confirm USD import functionality is availableVerify that the USD file import/load feature exists in the installed product. Check the File menu for Import options or verify the USD plugin/module is loaded in the software.Affected if USD import is not available or the USD plugin is not loaded, the attack surface does not exist.
-
Assess exposure to untrusted USD filesReview whether the system processes USD files from untrusted or unknown sources, such as downloaded files, email attachments, or collaborative workspaces.Affected if Users routinely open USD files from untrusted or unknown sources in the affected product.
If Arnold or 3ds Max is installed with a vulnerable version and the USD import feature is used to load files from untrusted sources, the environment is likely affected by CVE-2026-0659.

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.
From vendor dataAvoid opening untrusted or unknown USD files in affected Autodesk products until official patches are available; keep software updated with latest security releases.
