Summary
ThrottleStop.sys, a legitimate driver, exposes two IOCTL interfaces that allow arbitrary read and write access to physical memory via the MmMapIoSpace function. 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.

"value": "ThrottleStop.sys, un controlador leg\u00edtimo, expone dos interfaces IOCTL que permiten acceso arbitrario de lectura y escritura a la memoria f\u00edsica mediante la funci\u00f3n MmMapIoSpace. Esta implementaci\u00f3n insegura puede ser explotada por una aplicaci\u00f3n maliciosa en modo usuario para parchear el kernel de Windows en ejecuci\u00f3n e invocar funciones arbitrarias del kernel con privilegios de anillo 0. Esta vulnerabilidad permite a atacantes locales ejecutar c\u00f3digo arbitrario en el contexto del kernel, lo que resulta en una escalada de privilegios y posibles ataques posteriores, como la desactivaci\u00f3n del software de seguridad o la evasi\u00f3n de las protecciones a nivel de kernel. La versi\u00f3n 3.0.0.0 de ThrottleStop.sys y posiblemente otras se ven afectadas. Aplique las actualizaciones seg\u00fan las instrucciones del proveedor."
