CPUID CPU-Z Arbitrary Read/Write Privilege Elevation Vulnerability

CPUID CPU-Z is a free software package for collecting information about system devices. A security vulnerability exists in versions of CPUID CPU-Z prior to 1.43, which originates from a program that can send ioctl 0x9C402430 calls to the kernel mode driver to exploit the vulnerability by writing ...

Code injection

In CPUID CPU-Z before 1.43, there is an arbitrary memory write that results directly in elevation of privileges, because any program running on the local machine while CPU-Z is running can issue an ioctl 0x9C402430 call to the kernel-mode driver e.g., cpuz141x64.sys for version 1.41...
