I have a BE6000-M5 and on the ESXi mgmt page I see this warning: "This host is potentially vulnerable to issues described in CVE-2018-3646, please refer to https://kb.vmware.com/s/article/55636 for details and VMware recommendations"
Do I need to take action on this, i.e. disable hyperthreadingMitigation as described on the CVE?

Hello Gfolens,
It will depend on what UCSM Firmware your blades are on in order to determine if you are affected. Fixed firmware for blades is on 3.2.(3h).
Here is documentation for you: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvm03339

Strange, I'm running v4.0(2f) on both servers and both have the warning...

There are also hyper-visor specific changes that need to be applied. See KB articles from VMware:
https://kb.vmware.com/s/article/55636
https://kb.vmware.com/s/article/55806
You can also disable the warning if these are not production and you do not intend to resolve the issue.
There were also some fixes in the 6.7U2 vSphere, but I've not read through them yet.
