Apple has confirmed that all Macs, iPhones, iPads and other devices (bar Apple Watch) are vulnerable to the newly-revealed Spectre and Meltdown Intel, ARM and AMD processor vulnerabilities.
What’s the problem?
Taking advantage of a vulnerability that has been around for 20-years, Meltdown and Spectre exploit a CPU performance feature called “speculative execution”. Speculative execution exists to improve computer speed by enabling the processor to work on multiple instructions at once, sometimes in non-sequential order.
