Also, Android is safe if running security patch 2018-01-05. Which means millions of Android devices will never be safe and also current devices might not see an update for months.

 

 

If not tens or hundreds of millions of Devices, or perhaps even a billion devices (given there were 2 billion active android devices in early 2017)

AMD and Arm are affected https://Meltdownattack.com 




Opinions are my own and not the views of my employer.

Quote from that article:
At the moment, it is unclear whether ARM and AMD processors are also affected by Meltdown.

Yup but look at the Spectre details. :)

I applied a resent update for my bios and in the notes it say's 

 

''Update Intel ME for security vulnerabilities''

 

Do you think that it's to do with this or no?

So as I understand it (copied from reddit)

 

Basically it seems like there's two vulnerabilities, Spectre, a bug that allows applications to read other applications' memory, and Meltdown, a bug that allows applications to read system memory. Google tested four variants of these, a non-malicious variant of Spectre, two malicious ones of it and one malicious variant of Meltdown.

 

Of these Meltdown seems so far to be Intel "exclusive" while Spectre is universal, but only the non-malicious version of it. The malicious version of it only works on Intel when run in the default configuration and one of the two AMD parts Google tested (an A8-9600 APU) when run in a non-default configuration.

Against who? And for what?

 

A problem has been identified, and is being fixed.

Not a very good fix if the fix will reduce performance by 34%
