CVE-2017-15303
Estado: ModificadaAlta (7.8)—
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).
CVSS
- Versión: 3.0
- Vector: CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
