Intel BUG - speculative execution side-channel vulnerabilities

Intel has to finish and release them (possibly next week, I heard) before they will be available for Dell to integrate and package as BIOS updates. There is also a possibility that old machines won't even get BIOS updates to address it (those well outside of the support lifecycle - 9G and 10G and older, at least).

Here is where you should go for "guidance":

This is a curious position for Dell to be in given that there is evidence that they've been preparing for this for some time, here is one they have released. Yes, I know it is a desktop platform in a rack but their statement on client platforms is similar

This may be part of the reason that hardware vendors don't have all the information ready

"This vulnerability was originally scheduled to be made public on 9
January.  It was accelerated at the request of the discloser due to
one of the issues being made public."

May just back up what Intel said that they have been working on it for some time and were poised to announce it as soon as the fix was ready ... different platforms/technology may be affected differently and/or require different levels of fixes.

Just saw your post, along the same lines ...
