CVE-2025-7771 describes a critical vulnerability in ThrottleStop.sys, a legitimate driver, specifically version 3.0.0.0 and potentially others. This flaw allows malicious user-mode applications to achieve arbitrary physical memory read/write access via insecure IOCTL interfaces, enabling kernel patching and arbitrary kernel function execution with ring-0 privileges. The vulnerability carries a high CVSS score of 8.7 due to its local attack vector, high impact on confidentiality, integrity, and availability, and the potential for complete system compromise and security software bypass. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
