Detailsinfo

A vulnerability, which was classified as critical, was found in Hotta Studio 7.23.4.7. This affects an unknown code block in the library GameDriverX64.sys of the component IOCTL Handler. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability. The summary by CVE is:

The GameDriverX64.sys kernel-mode anti-cheat driver (v7.23.4.7 and earlier) contains an access control vulnerability in one of its IOCTL handlers. A user-mode process can open a handle to the driver device and send specially crafted IOCTL requests. These requests are executed in kernel-mode context without proper authentication or access validation, allowing the attacker to terminate arbitrary processes, including critical system and security services, without requiring administrative privileges.

This vulnerability is uniquely identified as CVE-2025-61155 since 09/26/2025. The exploitability is told to be easy. An attack has to be approached locally. Technical details are known, but no exploit is available.
