Name of the Vulnerable Software and Affected Versions BIG-IP Virtual Edition (VE) versions 13.1.0 through 13.1.3.4 BIG-IP Virtual Edition (VE) versions 14.1.0 through 14.1.2.6 BIG-IP Virtual Edition (VE) versions 15.0.0 through 15.0.1.3 BIG-IP Virtual Edition (VE) versions 15.1.0 through 15.1.0.3 BIG-IP Virtual Edition (VE) versions 16.0.0 through 16.0.0.1

Description The issue affects 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. These systems may fail and leave the Traffic Management Microkernel (TMM) in a state where it cannot transmit traffic.

Recommendations For versions 13.1.0 through 13.1.3.4, consider disabling SR-IOV on vSphere as a temporary workaround until a patch is available. For versions 14.1.0 through 14.1.2.6, consider disabling SR-IOV on vSphere as a temporary workaround until a patch is available. For versions 15.0.0 through 15.0.1.3, consider disabling SR-IOV on vSphere as a temporary workaround until a patch is available. For versions 15.1.0 through 15.1.0.3, consider disabling SR-IOV on vSphere as a temporary workaround until a patch is available. For versions 16.0.0 through 16.0.0.1, consider disabling SR-IOV on vSphere as a temporary workaround until a patch is available.
