Description
CVE-2025-61155 is an access control vulnerability in the GameDriverX64.sys kernel-mode anti-cheat driver version 7.23.4.7 and earlier. It allows a local non-administrative user-mode process to send crafted IOCTL requests that are executed in kernel mode without proper validation. This can lead to termination of arbitrary processes, including critical system and security services, causing system instability or denial of service. The vulnerability requires local access with low privileges and no user interaction. It has a medium severity with a CVSS score of 5.5.
