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: --------------- -> https://www.spinics.net/lists/kernel/msg3111012.html This issue was discovered by Jason Wang(CC'd) of Red Hat Inc. 'CVE-2019-3900' assigned by Red Hat Inc.
