Description Vladis Dronov 2016-01-04 16:04:09 UTC 
A design flaw found in the current Ethernet SRIOV NIC deployments that enables untrusted malicious virtual machines to completely control the network throughput and the latency of other unrelated VMs. The attack exploits Ethernet "pause" control frames, which enable network flow  control functionality.
