Probably none. In my experience (and I was a Lenovo employee until very recently) most - if not all - of the Lenovo employees understand that SuperFish / etc. were a huge mistake, and are very diligent about not doing anything that could be perceived as going down a similar path again.
Of course it's a big company and there may be somebody hidden away in some corner planning "SuperFish 2.0", but the people I interacted with with were all pretty committed to not engaging in those kinds of behaviors. Take that FWIW.
Disclosure: I was with Lenovo until recently, and I still have friends who work there, but I have no financial stake of any sort in this discussion.
