CVE-2019-18845 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. 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 AUTHORITY\SYSTEM privileges, by mapping \Device\PhysicalMemory into the calling process via ZwOpenSection and ZwMapViewOfSection.. EPSS estimates a 0.42% chance of exploitation in the next 30 days.
