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!
