Cisco NX-OS IP in IP Packet Processing Vulnerability for UCS 6200 series fiber interconnect?

[lasdcisco]

Has anyone aware of this issue?  here's the link for it:

Apparently 6200 and 6300 series FI are affected by this as well. Has anyone gone through remediation for this security vulnerability?

To be clear, the FIs are vulnerable only under certain circumstances:

"Cisco UCS Fabric Interconnects are affected only when NetFlow monitoring is enabled on the device and a flow exporter profile is configured with a source IP address set for the exporter interface"

The workaround for FIs, would be to turn off netflow, until fixed code comes out (which will be this month):

UCS 6200 and 6300 Series Fabric Interconnects:
