CVE-2025-9458

Code execution via malformed PRT heap overflow

Published Nov 7, 2025 · Updated Nov 7, 2025

Heap-based buffer overflow in Autodesk Shared Components 2026.3 allows attackers to execute code by opening a malicious PRT file. Autodesk identifies the shared PRT parser and heap-based overflow, but has not disclosed the faulty routine or bounds operation. Exploitation requires user interaction and runs code in the current process, bounding the result to that process's privileges.
