Code execution via unchecked 3DM object write
Published Jun 25, 2024 · Updated Aug 26, 2025
Out-of-bounds write in ASMkern229A.dll in Autodesk AutoCAD-based products 2022 through 2025 allows attackers to execute code via a crafted 3DM file. The ASMkern229A.dll 3DM handler fails to validate user-supplied object dimensions before writing past the end of an allocated object. Exploitation requires a user to open the file or visit malicious content, and successful execution runs in the current process context; failed attempts can crash the process or corrupt data.

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
