Apple Meltdown And Spectre
Somewhat confusing is the passage, in which the concerns from Apple is dedicated to the Meltdown gap. Apple has already distributed countermeasures for iOS 11.2, macOS 10.13.2 and tvOS 11.2.
There is also on Reddit an interesting discussion: Because the fact is that Apple uses ARM designs or components thereof since A7, but still cooks its own soup. Of course, it does not disclose which technology components are used by ARM. Because ARM has confirmed on its side, that “variant 3”, ie Meltdown, also occurs in the Cortex-A75 design. There is also a Variant 3a (Cortex-A15, Cortex-A57 and Cortex-A72), but here ARM writes that probably no countermeasures are necessary.
