**Name of the Vulnerable Software and Affected Versions** MSI Feature Manager (affected versions not specified) **Description** A local privilege escalation issue exists in the `KernCoreLib64.sys` kernel driver. A locally logged-on user can perform arbitrary physical memory read/write and unrestricted I/O port operations by accessing exposed IOCTL (Input/Output Control) handlers without administrator privileges. This allows attackers to manipulate kernel objects, tamper with kernel-mode callbacks, bypass Protected Process Light (PPL) protections, and disable security software. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
