Summary
[none]
Details

An infinite loop issue was found in the vhostnet kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handlerx(). 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.
