CVE-2024-36054

Kernel privilege escalation via unrestricted mapping IOCTLs

Published May 26, 2024 · Updated Feb 13, 2025

Kernel memory disclosure in Marvin Test Solutions Hardware Access Driver before 5.0.5.0 allows local users to gain all privileges. Hw64.sys services IOCTL 0x9c4064b8 through MmMapIoSpace and IOCTL 0x9c406490 through ZwMapViewOfSection, mapping caller-selected kernel memory into user mode. Local code execution is required; successful reads expose kernel memory and enable full privilege escalation.
