      <title>CVE-2026-68379 — tcp: fix TIME_WAIT socket reference leak on PSP policy failure</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-68379</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 TIME_WAIT socket reference leak on PSP policy failure&lt;/p&gt;
&lt;p&gt;Release the TIME_WAIT socket reference and jump to discard_it
upon PSP policy failure in both IPv4 and IPv6 receive paths.
This prevents a memory leak of tcp_tw_bucket structures.&lt;/p&gt;</description>
