## Overview

In the Linux kernel, the following vulnerability has been resolved:

cpufreq: amd-pstate-ut: Skip tests when amd-pstate driver is not active

The crash issue may occur when modprobe amd_pstate_ut on intel platform.

   amd_pstate_ut: 1    amd_pstate_ut_acpi_cpc_valid  success!
   amd_pstate_ut: 2    amd_pstate_ut_check_enabled   success!
