Billions of smartphones – including iPhones – could be affected by ‘worst ever chip flaw’

Mobile users who thought they were unaffected by the Meltdown flaw affecting Intel chips are suddenly not quite so secure.

This means that all mobile devices that use ARM architecture (and that’s pretty much all of them) are now in danger of attack.
