      <title>CVE-2022-50781 — amdgpu/pm: prevent array underflow in vega20_odn_edit_dpm_table()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2022-50781</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;amdgpu/pm: prevent array underflow in vega20_odn_edit_dpm_table()&lt;/p&gt;
&lt;p&gt;In the PP_OD_EDIT_VDDC_CURVE case the &amp;#34;input_index&amp;#34; variable is capped at
2 but not checked for negative values so it results in an out of bounds
read.  This value comes from the user via sysfs.&lt;/p&gt;</description>
