**Name of the Vulnerable Software and Affected Versions** Genshin Impact mhyprot2.sys version 1.0.0.0 **Description** The Genshin Impact mhyprot2.sys anti-cheat driver does not adequately restrict unprivileged function calls, allowing local, unprivileged users to execute arbitrary code with SYSTEM privileges on Microsoft Windows systems. The mhyprot2.sys driver must first be installed by a user with administrative privileges. **Recommendations** For Genshin Impact mhyprot2.sys version 1.0.0.0, consider uninstalling or disabling the driver to prevent exploitation until a patch is available. As a temporary workaround, restrict access to the system to minimize the risk of local, unprivileged users executing arbitrary code with SYSTEM privileges.
