      <link>https://cve.radiocsirt.org/vuln/cve-2026-89438</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;platform/x86: ISST: Validate logical CPU id and clos id&lt;/p&gt;
&lt;p&gt;Validate max CLOS ID and logical CPU ID for core power feature.
Reject any clos level or logical CPU number greater than the
supported maximum. These are used to calculate MMIO offset.&lt;/p&gt;</description>
