Are Android Snapdragon Vulnerabilities a Real-World threat already?

@Wish_Wu recently did a demonstration of these exact security vulnerabilities to full exploitation at the HITBSecConf in Amsterdam.

Here is the slide deck.

The bugs involve the perf_event_open capabilities shipped in many Android OSes including the recent Nexus line of phones as well as many Samsung Galaxy and LG Android phones of recent note. Wish_Wu goes over which ones are likely in the prezo above.

CyanogenMod also reviewed these vulnerabilities.

There is also additional detail on CVE-2016-0819 including Qualcomm patch (information here).

By searching for the Android IDs in Wish Wu's presentation, you can also see the Android OS and other CyanogenMod patches. The presentation also goes over some additional fuzzing suites that will aid in exploit development.
