CVE-2022-41303

Code execution via malicious FBX use-after-free

Published Oct 14, 2022 · Updated May 14, 2025

Use-after-free in Autodesk FBX SDK 2020.3.1 allows attackers to execute arbitrary code when a user opens a malicious FBX file. During FBX parsing, the SDK references a freed memory location whose contents can be controlled by an attacker, redirecting execution in the host process. Exploitation requires user interaction and runs code with the privileges of the application that processes the file.
