      <title>CVE-2026-80735 — ovpn: ensure socket is owned by ovpn before deref sk_user_data</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-80735</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;ovpn: ensure socket is owned by ovpn before deref sk_user_data&lt;/p&gt;
&lt;p&gt;Some subsystems, like BPF SOCKMAP, set sk_user_data without
actually setting the encap_type.&lt;/p&gt;
&lt;p&gt;For this reason, we must make sure that the type is the
one ovpn expects before dereferencing sk_user_data.&lt;/p&gt;
&lt;p&gt;Failing to do so may lead to out-of-bounds reads.&lt;/p&gt;</description>
