      <title>CVE-2024-50169 — vsock: Update rx_bytes on read_skb()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2024-50169</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;vsock: Update rx_bytes on read_skb()&lt;/p&gt;
&lt;p&gt;Make sure virtio_transport_inc_rx_pkt() and virtio_transport_dec_rx_pkt()
calls are balanced (i.e. virtio_vsock_sock::rx_bytes doesn&amp;#39;t lie) after
vsock_transport::read_skb().&lt;/p&gt;
&lt;p&gt;While here, also inform the peer that we&amp;#39;ve freed up space and it has more
credit.&lt;/p&gt;
&lt;p&gt;Failing to update rx_bytes after packet is dequeued leads to a warning on
SOCK_STREAM recv():&lt;/p&gt;
&lt;p&gt;[  233.396654] rx_queue is empty, but rx_bytes is non-zero
[  233.396702] WARNING: CPU: 11 PID: 40601 at net/vmw_vsock/virtio_transport_common.c:589&lt;/p&gt;</description>
