CVE-2020-14979
The WinRing0.sys and WinRing0x64.sys drivers 1.2.0 in EVGA Precision X1 through 1.0.6 allow local users, including low integrity processes, to read and write to arbitrary memory locations.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.60%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The WinRing0.sys and WinRing0x64.sys drivers 1.2.0 in EVGA Precision X1 through 1.0.6 allow local users, including low integrity processes, to read and write to arbitrary memory locations. This allows any user to gain NT AUTHORITY\SYSTEM privileges by mapping \Device\PhysicalMemory into the calling process.
