      <title>CVE-2023-52649 — drm/vkms: Avoid reading beyond LUT array</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2023-52649</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/vkms: Avoid reading beyond LUT array&lt;/p&gt;
&lt;p&gt;When the floor LUT index (drm_fixp2int(lut_index) is the last
index of the array the ceil LUT index will point to an entry
beyond the array. Make sure we guard against it and use the
value of the floor LUT index.&lt;/p&gt;
&lt;p&gt;v3:
 - Drop bits from commit description that didn&amp;#39;t contribute
   anything of value&lt;/p&gt;</description>
