CVE-2026-92211 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 7.8 (high) and affects OpenUSD; no fixed version is listed yet.

## Summary

Pixar's OpenUSD library, which processes Universal Scene Description files such as USDC and USDZ, is affected. An attacker who gets a crafted file processed by the library could trigger a double free and run arbitrary code within the affected application's process.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Pixar Animation Studio OpenUSD: v26.03

## Description

Pixar Animation Studio OpenUSD Crate File Parsing Double Free Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Pixar Animation Studio OpenUSD. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the parsing of USDC and USDZ files. The issue results from the lack of validating the existence of an object prior to performing further free operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-30428.

## FAQ

### Is CVE-2026-92211 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

### What does this mean?

The flaw is a double free in the OpenUSD crate file parser, triggered when USDC or USDZ files are parsed. According to the advisory, it could allow arbitrary code to run in the context of the current process.

### Which versions are affected by CVE-2026-92211?

OpenUSD: version v26.03.

Source: https://cve.now/CVE-2026-92211

### Am I affected, and how do I check?

The facts list no version ranges, so the affected versions are not stated. The affected setup is processing USDC or USDZ files with the OpenUSD crate file parser, so a reader can check whether their OpenUSD build handles those file types.

### How do I fix CVE-2026-92211?

The facts name no fixed version or update target. Check the vendor's advisory for a patched release before deciding what to install.

Source: https://www.zerodayinitiative.com/advisories/ZDI-26-791/

### What if there's no patch?

The facts list no workaround. The only stated trigger is processing USDC or USDZ files with the crate parser, so limiting that processing is the one lever the facts point to.

Source: https://www.zerodayinitiative.com/advisories/ZDI-26-791/

### Why do the sources disagree?

The description calls this a remote vulnerability, but the CVSS vector records the attack vector as local (AV:L). The sources conflict on how the attack is delivered, and the facts do not resolve which is correct.
