This insecure implementation can be exploited by a malicious user-mode application to patch the running Windows kernel and invoke arbitrary kernel functions with ring-0 privileges. The vulnerability enables local attackers to execute arbitrary code in kernel context, resulting in privilege escalation and potential follow-on attacks, such as disabling security software or bypassing kernel-level protections. ThrottleStop.sys version 3.0.0.0 and possibly others are affected. Apply updates per vendor instructions."},{"lang":"es","value":"ThrottleStop.sys, un controlador legítimo, expone dos interfaces IOCTL que permiten acceso arbitrario de lectura y escritura a la memoria física mediante la función MmMapIoSpace.
