      <title>CVE-2026-80972 — ALSA: aloop: Check card index validity at probe</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-80972</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;ALSA: aloop: Check card index validity at probe&lt;/p&gt;
&lt;p&gt;aloop driver blindly trusts that the given devptr-&amp;gt;id value is within
the proper card index range at probe.  It&amp;#39;s OK for the devices the
driver itself creates at the module probe time, but if the device is
bound manually via sysfs interface, this could be -1 as &amp;#34;none&amp;#34;, and
this leads to OOB access for index[] and other parameters.&lt;/p&gt;
&lt;p&gt;Add a sanity check for the card index and warn/correct it if it&amp;#39;s a
value out of the range.&lt;/p&gt;</description>
