Subject: CVE-2019-3900 Kernel: vhost_net: infinite loop while receiving
 packets leads to DoS


An infinite loop issue was found in the vhost_net kernel module, while 
handling incoming packets in handle_rx(). It could occur if one end sends 
packets faster than the other end can process them.

A guest user, maybe remote one, could use this flaw to stall the vhost_net 
kernel thread, resulting in a DoS scenario.

Upstream patch:

This issue was discovered by Jason Wang(CC'd) of Red Hat Inc.
'CVE-2019-3900' assigned by Red Hat Inc.

Thank you.
