CVE-2025-6631

Code execution via crafted PRT parsing

Published Jul 29, 2025 · Updated May 8, 2026

Out-of-bounds write in Autodesk Shared Components allows context-dependent attackers to execute code through a crafted PRT file. Autodesk has not disclosed the affected parser routine or the operation that writes beyond its destination buffer. The affected range starts at 1.6.2.11 and ends before 1.7.0.10, and a user must cause a host product to parse the file; exploitation can instead crash the process or corrupt data.
