CVE-2026-57851 (GCVE-0-2026-57851)

Vulnerability from cvelistv5 – Published: 2026-07-07 16:02 – Updated: 2026-07-09 18:50

Title
MSI KernCoreLib64.sys Privilege Escalation via IOCTL Handlers
Summary
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.
