      <title>CVE-2026-43436 — ALSA: usb-audio: Check endpoint numbers at parsing Scarlett2 mixer interfaces</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-43436</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: usb-audio: Check endpoint numbers at parsing Scarlett2 mixer interfaces&lt;/p&gt;
&lt;p&gt;The Scarlett2 mixer quirk in USB-audio driver may hit a NULL
dereference when a malformed USB descriptor is passed, since it
assumes the presence of an endpoint in the parsed interface in
scarlett2_find_fc_interface(), as reported by fuzzer.&lt;/p&gt;
&lt;p&gt;For avoiding the NULL dereference, just add the sanity check of
bNumEndpoints and skip the invalid interface.&lt;/p&gt;</description>
