      <title>CVE-2025-68246 — ksmbd: close accepted socket when per-IP limit rejects connection</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2025-68246</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;ksmbd: close accepted socket when per-IP limit rejects connection&lt;/p&gt;
&lt;p&gt;When the per-IP connection limit is exceeded in ksmbd_kthread_fn(),
the code sets ret = -EAGAIN and continues the accept loop without
closing the just-accepted socket. That leaks one socket per rejected
attempt from a single IP and enables a trivial remote DoS.&lt;/p&gt;
&lt;p&gt;Release client_sk before continuing.&lt;/p&gt;
&lt;p&gt;This bug was found with ZeroPath.&lt;/p&gt;</description>
