Summary
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., cpuz141_x64.sys for version 1.41).
Exploit prediction
1.59% chance of exploitation in the next 30 days, higher than 75% of all scored CVEs (FIRST EPSS, 2026-11-08).
