The kernel in Microsoft Windows 8.1, Windows Server 2012 Gold and R2, Windows RT 8.1, and Windows 10 Gold, 1511, and 1607 allows local users to gain privileges via a crafted application that makes an API call to access sensitive information in the registry, aka "Windows Kernel Local Elevation of Privilege Vulnerability," a different vulnerability than CVE-2016-0073.
The Windows DeviceApi CMApi PiCMOpenClassKey IOCTL allows a normal user to create arbitrary registry keys in the system hive leading to elevation of privilege.
