What is CVE-2019-16098?

The MSI Afterburner software contains a vulnerability in its driver components, RTCore64.sys and RTCore32.sys, which enables authenticated users to read and write to arbitrary regions of memory and I/O ports. This vulnerability may be leveraged for privilege escalation, allowing malicious actors to execute code with elevated permissions and disclose sensitive information. Additionally, the fact that these drivers are signed presents a risk of bypassing the Microsoft driver-signing policy, potentially facilitating the deployment of malicious software on affected systems.

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.
