CVE-2022-41305

Memory corruption via malformed PKT write violation

Published Oct 14, 2022 · Updated May 14, 2025

Out-of-bounds write in Autodesk Subassembly Composer 2020 through 2023 allows attackers to corrupt memory via a crafted PKT file. SubassemblyComposer.exe mishandles untrusted PKT data and performs an invalid memory write while consuming the file. A user must open the file; the direct consequence is process memory corruption, and exploitation with other flaws can execute code in that process.
