Code execution via X_B/X_T object use-after-free
Published Jun 25, 2024 · Updated Aug 27, 2025
Use-after-free in pskernel.DLL in Autodesk AutoCAD-based products allows remote attackers to execute code through a crafted X_B or X_T file. The X_T parser performs operations on an object without first validating that it still exists, leaving freed memory reachable during parsing. A user must visit a malicious page or open the file, and successful exploitation runs code in the current application process on Windows.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=2022 <2022.1.5
- Affected versionversion=2023 <2023.1.6
- Affected versionversion=2024 <2024.1.5
