An infinite loop issue was found in the vhost_net kernel module while handling incoming packets in handle_rx(). The infinite loop could occur if one end sends packets faster than the other end can process them. A guest user, maybe a remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario.
