      <title>CVE-2025-21927 — nvme-tcp: fix potential memory corruption in nvme_tcp_recv_pdu()</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2025-21927</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;nvme-tcp: fix potential memory corruption in nvme_tcp_recv_pdu()&lt;/p&gt;
&lt;p&gt;nvme_tcp_recv_pdu() doesn&amp;#39;t check the validity of the header length.
When header digests are enabled, a target might send a packet with an
invalid header length (e.g. 255), causing nvme_tcp_verify_hdgst()
to access memory outside the allocated area and cause memory corruptions
by overwriting it with the calculated digest.&lt;/p&gt;
&lt;p&gt;Fix this by rejecting packets with an unexpected header length.&lt;/p&gt;</description>
