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

CVE-2023-53780 [MEDIUM] CWE-191 kernel: drm/amd/display: fix FCLK pstate change underflow
kernel: drm/amd/display: fix FCLK pstate change underflow
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
A calculation flaw was found in the AMD display driver in the Linux kernel. When UCLK p-state is not supported, FCLK p-state change watermarks are incorrectly calculated using dummy values, potentially causing underflow. This can lead to display issues or system instability during power state transitions.
Statement: This is a driver logic bug affecting AMD display p
