Google confirms Android attacks; no fix for most Samsung users

I'm really struggling to find any concrete information about what this vulnerability actually is. Does anyone know where to look for a good summary?

Search CVE numbers.

Basically, just like most things these days, its all just local privilege escalation. This means that you have to install/run an app that has these exploits built in.

Soif you usage profile doesn't include downloading apps from untrusted sources, you don't need to worry.

What if an existing app gets an update that exploits the vulnerability?

For sure that's not going to happen to an app released by a major company, but there are lots of less known app created by many different developers.
