What are Spectre & Meltdown ?
Intel, ARM and AMD have been shown to share critical design flaws in their computer chips that compromise security. The flaws have been called Spectre & Meltdown. The flaws have been present for 18+ years.
The flaws were discovered by Google (amongst others), who have warned that a hacker / attacker could use the flaws to steal sensitive or confidential information.
Who is affected ?
Pretty much every PC, Laptop, Tablet & smartphone is affected by the flaw regardless of manufacturer or whether you run Microsoft Windows, MAC OSX, IOS etc.
What is a Computer Chip / Processor ?
A CPU or Central Processing Unit is the brain of a Computer.
A CPU is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output operations specified.
Am I in Immediate Danger ?
Intel and Google have both stated that they have not seen any attacks from these two flaws in the wild to date, so that is good news.
Meltdown primarily is targeted at Intel processors, although ARM (who make chips for iPhones) have said their chips are vulnerable too.
Google has said they have been able to execute Spectre attacks on processors from just about all manufactures (Intel, ARM and AMD). According to Google there is no simple single fix.
It is much harder to pull off a Spectre based attack.
