Summary
OpenUSD File Parsing Use-After-Free Remote Code Execution Vulnerability
We have been advised by Zero Day Initiative that our usage of the USD framework may constitute a Use-After-Free Remote Code Execution Vulnerability. They have sent us the attached file illustrating the issue. Indeed, we see a use after free exception when running the file through our importer with an address sanitizer.
Thanks in advance.
Impact
Memory is accessed after it has been freed, leading to undefined behavior in native code. Typical impact: memory corruption, crash, or potential code execution.
Affected versions
Security releases
Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is GHSA-GRJP-54V3-C442? GHSA-GRJP-54V3-C442 is a medium-severity use after free vulnerability in usd-core (pip), affecting versions <= 25.08. It is fixed in 25.11. Memory is accessed after it has been freed, leading to undefined behavior in native code.
- Which versions of usd-core are affected by GHSA-GRJP-54V3-C442? usd-core (pip) versions <= 25.08 is affected.
- Is there a fix for GHSA-GRJP-54V3-C442? Yes. GHSA-GRJP-54V3-C442 is fixed in 25.11. Upgrade to this version or later.
- Is GHSA-GRJP-54V3-C442 exploitable, and should I be worried? Whether GHSA-GRJP-54V3-C442 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether GHSA-GRJP-54V3-C442 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
