AI-Generated

The vulnerability in the KernCoreLib64.sys kernel driver allows any locally logged-on user to escalate privileges, enabling arbitrary read/write operations on physical memory and unrestricted access to I/O ports without requiring administrative rights. This flaw can be exploited to manipulate kernel objects, bypass security measures, and disable security software, posing a significant risk to system integrity. Organizations using affected systems should prioritize patching this vulnerability to mitigate potential exploitation by malicious actors.

Original NVD Description

MSI Feature Manager contains a local privilege escalation vulnerability in the KernCoreLib64.sys kernel driver that allows any locally logged-on user to perform arbitrary physical memory read/write and unrestricted I/O port operations by accessing exposed IOCTL handlers without administrator privileges. Attackers can exploit the accessible device object through IOCTL handlers to manipulate kernel objects, tamper with kernel-mode callbacks, bypass Protected Process Light protections, and disable security software.
