CVE-2022-41308

Code execution via unchecked PKT decoder write

Published Oct 14, 2022 · Updated May 14, 2025

Out-of-bounds write in Autodesk Subassembly Composer 2020 through 2023 allows attackers to execute code via a crafted PKT file. The PKT decoder fails to enforce a bounds check before writing malformed file data, corrupting memory outside the intended buffer. Exploitation requires the file to be processed locally, and successful code execution runs in the SubassemblyComposer.exe process context.
