Estado: RecibidaSin puntuar—
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.
Add state detection to amd pstate driver to prevent amd_pstate_ut driver from testing on non-AMD platforms.
