CVE-2025-6636

Code execution via unchecked PRT object use

Published Jul 29, 2025 · Updated May 8, 2026

Use-after-free in Autodesk Shared Components allows attackers to execute code by opening a maliciously crafted PRT file. The PRT parser performs operations on an object without first validating that the object still exists, leaving an invalid reference after it is freed. Exploitation requires user interaction and runs code in the current process; the same fault can instead crash the process or expose sensitive data.
