      <title>CVE-2024-57914 — usb: typec: tcpci: fix NULL pointer issue on shared irq case</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2024-57914</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;usb: typec: tcpci: fix NULL pointer issue on shared irq case&lt;/p&gt;
&lt;p&gt;The tcpci_irq() may meet below NULL pointer dereference issue:&lt;/p&gt;
