CVE-2025-51060 describes a vulnerability in CPUID cpuz.sys version 1.0.5.4, allowing an attacker to execute arbitrary code in the kernel context on 64-bit Windows systems where core isolation is disabled. By manipulating DeviceIoControl parameters, an attacker can perform RDMSR and WRMSR operations to hook KiSystemCall64 and then use Return-Oriented Programming to disable SMAP and execute user-mode syscall handlers. This vulnerability has a CVSS score of 6.5 (MEDIUM), indicating a network-exploitable flaw with low impact on confidentiality and integrity, but no active exploitation, public exploit code, or significant community discussion has been observed.
