CVE-2022-42946

Code execution via malformed model-file parsing

Published Dec 19, 2022 · Updated Apr 17, 2025

An out-of-bounds read in Autodesk Maya 2022 and 2023 allows remote attackers to execute code through a crafted X_B or PRT file. The X_B and PRT parsers fail to validate user-supplied data before reading past the end of an allocated buffer. Exploitation requires the target to open the file or visit a malicious page, and code execution occurs in the current process and may require chaining with another flaw.
