GHSA-62C9-HJFX-22HH
Vulnerability from github – Published: 2026-09-04 21:31 – Updated: 2026-09-04 21:31
VLAI
Details
PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain a privilege escalation vulnerability in DirectIo64.sys that allows local users to modify hardware configuration by exploiting exposed IOCTLs with no validation on device selection, register offset, or value. Attackers can obtain a device handle and issue arbitrary PCI configuration space read/write operations to enable Bus Master DMA on any PCI device, halt storage controller I/O by clearing command registers, or remap Base Address Registers to redirect DMA to an attacker-chosen physical address.

Details
A potential insufficient access control vulnerability was reported in the Lenovo Dispatcher 3.0 and Dispatcher 3.1 drivers used by some Lenovo consumer notebooks that could allow an authenticated local user to execute code with elevated privileges. The Lenovo Dispatcher 3.2 driver is not affected. This vulnerability does not affect systems when the Windows feature Core Isolation Memory Integrity is enabled. Lenovo systems preloaded with Windows 11 have this feature enabled by default.

Details
The MBStorage DRAM lighting control module within Gigabyte Control Center (GCC) developed by GIGABYTE Technology has an Improper Access Control vulnerability. Authenticated local attackers can send specific IOCTL commands through the driver MyPortIO_x64.sys bundled with the module, thereby arbitrarily reading and writing physical memory and obtaining kernel-level privileges.
