I hope I don't hijack this thread, but I'd also like to know this for the 6th gen NUCs (Skylake), including the KYK.
So for NUC7i3*, NUC7i5*, NUC7i7*, the question is: Which BIOS update addresses Intel processor errata KBL095, KBW095 or the similar one for the respective Kaby Lake CPUs used?
For NUC6i3*, NUC6i5*, NUC6i7*, the question is: Which BIOS update addresses Intel processor erratum SKW144, SKL150, SKX150, SKZ7, or the similar one for the respective Skylake CPUs used?
While this problem was noticed on Linux, the erratum causes malfunction (including wrong calculation / results) regardless of OS as long as hyperthreading is enabled (the default).
According to the reports, the erratum can cause issues when HT is enabled on any platforms that utilize 6th generation Skylake or 7th generation Kaby Lake Core processors. 6th generation Skylake Core processors are found in the (previous-generation) KY (NUC6i7KYK) and SY (NUC6i[3|5]SY[K|H]) NUC models and 7th generation Kaby Lake Core processors are found in the (current-generation) BN (NUC7i[3|5|7]BN[K|H]) NUC models.
It appears that I have been one of the lucky ones; in all my testing with these various NUC models, have never seen the issue manifest in any way. I have, however, read plenty of posts from folks who have suffered application crashes, BSODs, spontaneous system resets, etc. that could (and most likely are) the result of this erratum manifesting.
As yet, I have seen no formal statement from the Intel NUC development/sustaining team regarding the availability of BIOS releases that include the necessary microcode update. I hope they will post something fairly soon...
Does this issue effect Desktop Skylake processors and Kabylake processors? I hope Intel is looking into it.
The issue: "
This advisory is about a processor/microcode defect recently identified
on Intel Skylake and Intel Kaby Lake processors with hyper-threading
enabled. This defect can, when triggered, cause unpredictable system
behavior: it could cause spurious errors, such as application and system
misbehavior, data corruption, and data loss."

Hope this helps
The likelihood of running into this issue is low. A fix for this issue is available and started rollout out to system manufacturers in April 2017. Intel recommends checking to make sure your BIOS is up to date.
