CVE-2019-18845
The MsIo64.sys and MsIo32.sys drivers in Patriot Viper RGB before 1.1 allow local users (including low integrity processes) to read and write to arbitrary memory locations, and consequently gain NT AUTHORITYSYSTEM privileges, by mapping DevicePhysicalMemory into the calling process via ZwOpenSection and ZwMapViewOfSection.
