This vulnerability (CVE-2025-6637) is an out-of-bounds write (CWE-787) in Autodesk Shared Components version 1.6.2.11. It occurs when a specially crafted PRT file is parsed by certain Autodesk products, allowing a malicious actor to write outside the intended memory bounds. The CVSS 3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability. Exploitation requires local access and user interaction, with low attack complexity and no privileges required. No known exploits are reported in the wild, and no patch or vendor advisory has been provided yet.

Exploitation can cause application crashes, data corruption, or arbitrary code execution in the context of the current process. This can lead to compromise of the affected system's confidentiality, integrity, and availability. The vulnerability requires local access and user interaction, limiting remote exploitation possibilities.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, avoid opening untrusted PRT files and restrict local access to trusted users only.
