K75111593 : BIG-IP VE network interface vulnerability CVE-2020-5939

Security Advisory Description

BIG-IP Virtual Edition (VE) systems on VMware, with an Intel-based 85299 Network Interface Controller (NIC) card and Single Root I/O Virtualization (SR-IOV) enabled on vSphere, may fail and leave the Traffic Management Microkernel (TMM) in a state where it cannot transmit traffic. (CVE-2020-5939)

Impact

TMM fails to process traffic, resulting in service disruption. If the affected BIG-IP system is configured as part of a device group, the system triggers a failover to the peer device.
