CVE-2017-15303
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…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.53%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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).
