Description (CNA)
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.
