      <title>CVE-2026-31537 — smb: server: make use of smbdirect_socket.send_io.bcredits</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-31537</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;smb: server: make use of smbdirect_socket.send_io.bcredits&lt;/p&gt;
&lt;p&gt;It turns out that our code will corrupt the stream of
reassabled data transfer messages when we trigger an
immendiate (empty) send.&lt;/p&gt;
&lt;p&gt;In order to fix this we&amp;#39;ll have a single &amp;#39;batch&amp;#39; credit per
connection. And code getting that credit is free to use
as much messages until remaining_length reaches 0, then
the batch credit it given back and the next logical send can
happen.&lt;/p&gt;</description>
