Not sure what to make of this wording. Thinly veiled threat? Hint that other embargoes are in place?
AMD had a similar vulnerability recently (Zenbleed) that used speculative evaluation misprediction to create an effective "use-after-free" bug that would reveal the contents of the internal SIMD register file https://lock.cmpxchg8b.com/zenbleed.html, that might be what is being referenced here.
