An infinite loop issue was found in the vhost_net kernel module in Linux
Kernel up to and including v5.1-rc6, 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.
