CVE-2023-27915

Memory corruption via X_B read access violation

Published Apr 14, 2023 · Updated Feb 6, 2025

Memory corruption in Autodesk AutoCAD 2023 allows context-dependent attackers to trigger a read access violation via a crafted X_B file. The X_B parser performs an undisclosed invalid read while processing malformed file data; Autodesk has not identified the affected function or parsing operation. A user must open or import the file, and this flaw enables code execution in the current process only when combined with other vulnerabilities.
