Last night while i was going through my news feed i found this https://www.bleepingcomputer.com/news/security/every-android-device-since-2012-impacted-by-rampage-vulnerability/ and was wondering how likely is this to happen.
Brand new and very few details so far. Right now it doesn't appear to have any working expploits in the wild:

Likelyhood now is low but this should get patched ASAP.
