      <title>CVE-2023-53780 — drm/amd/display: fix FCLK pstate change underflow</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2023-53780</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;drm/amd/display: fix FCLK pstate change underflow&lt;/p&gt;
&lt;p&gt;[Why]
Currently we set FCLK p-state change
watermark calculated based on dummy
p-state latency when UCLK p-state is
not supported&lt;/p&gt;
&lt;p&gt;[How]
Calculate FCLK p-state change watermark
based on on FCLK pstate change latency
in case UCLK p-state is not supported&lt;/p&gt;</description>
