      <title>CVE-2024-26936 — ksmbd: validate request buffer size in smb2_allocate_rsp_buf()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2024-26936</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: validate request buffer size in smb2_allocate_rsp_buf()&lt;/p&gt;
&lt;p&gt;The response buffer should be allocated in smb2_allocate_rsp_buf
before validating request. But the fields in payload as well as smb2 header
is used in smb2_allocate_rsp_buf(). This patch add simple buffer size
validation to avoid potencial out-of-bounds in request buffer.&lt;/p&gt;</description>
