      <title>CVE-2024-53206 — tcp: Fix use-after-free of nreq in reqsk_timer_handler().</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2024-53206</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;tcp: Fix use-after-free of nreq in reqsk_timer_handler().&lt;/p&gt;
&lt;p&gt;The cited commit replaced inet_csk_reqsk_queue_drop_and_put() with
__inet_csk_reqsk_queue_drop() and reqsk_put() in reqsk_timer_handler().&lt;/p&gt;
&lt;p&gt;Then, oreq should be passed to reqsk_put() instead of req; otherwise
use-after-free of nreq could happen when reqsk is migrated but the
retry attempt failed (e.g. due to timeout).&lt;/p&gt;
&lt;p&gt;Let&amp;#39;s pass oreq to reqsk_put().&lt;/p&gt;</description>
