      <title>CVE-2024-35785 — tee: optee: Fix kernel panic caused by incorrect error handling</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2024-35785</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;tee: optee: Fix kernel panic caused by incorrect error handling&lt;/p&gt;
&lt;p&gt;The error path while failing to register devices on the TEE bus has a
bug leading to kernel panic as follows:&lt;/p&gt;
