What is CVE-2020-14979?

The WinRing0.sys and WinRing0x64.sys drivers found in EVGA Precision X1 versions up to 1.0.6 contain a vulnerability that allows local users and low integrity processes to read from and write to arbitrary memory locations. This vulnerability enables attackers to escalate privileges to NT AUTHORITY\SYSTEM by mapping \Device\PhysicalMemory into their processes, potentially compromising system security.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
