      <title>CVE-2024-43873 — vhost/vsock: always initialize seqpacket_allow</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2024-43873</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;vhost/vsock: always initialize seqpacket_allow&lt;/p&gt;
&lt;p&gt;There are two issues around seqpacket_allow:
1. seqpacket_allow is not initialized when socket is
   created. Thus if features are never set, it will be
   read uninitialized.
2. if VIRTIO_VSOCK_F_SEQPACKET is set and then cleared,
   then seqpacket_allow will not be cleared appropriately
   (existing apps I know about don&amp;#39;t usually do this but
    it&amp;#39;s legal and there&amp;#39;s no way to be sure no one relies
    on this).&lt;/p&gt;
&lt;p&gt;To fix:
	- initialize seqpacket_allow after allocation
	- set it unconditionally in set_features&lt;/p&gt;</description>
