Graphics en Microsoft Windows 7 SP1, Windows Server 2008 SP2 y R2 SP1, Windows 8.1 y Windows RT 8.1, Windows Server 2012 y R2, Windows 10 versiones Gold, 1511, 1607, 1703 y Windows Server 2016, permite una vulnerabilidad de escalada de privilegios debido a la manera en que se manejan los objetos en la memoria, tambiƩn se conoce como "Win32k Elevation of Privilege Vulnerability".

This vulnerability allows local attackers to escalate privileges on vulnerable installations of Microsoft Windows. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the win32kfull.sys driver. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to escalate privilege to the level of SYSTEM.
