In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: fix FCLK pstate change underflow
[Why] Currently we set FCLK p-state change watermark calculated based on dummy p-state latency when UCLK p-state is not supported
[How] Calculate FCLK p-state change watermark based on on FCLK pstate change latency in case UCLK p-state is not supported
