A MAJOR SECURITY FLAW has been discovered in a handful of Samsung smartphones and tablets that could leave the devices open to attackers.

The vulnerability is in Samsung's Exynos processor chip and has been revealed by a hacker at XDA Developers forum.

This exploit, discovered by somebody who calls themself Alephzain at the XDA Developers forum, gives developers and potentially malware access to the RAM of Samsung devices. This means that users' data is accessible to developers and also means that the device could be bricked or wiped.

Alephzain said, "The good news is we can easily obtain root on these devices and the bad is there is no control over it.

"Ram dump, kernel code injection and others could be possible via app installation from Play Store. It certainly exists many ways to do that but Samsung give an easy way to exploit.

"This security hole is dangerous and expose phone to malicious apps."

The exploit affects a number of Samsung devices, including the Galaxy S2, Galaxy S3 and Galaxy Note, along with any other devices using Samsung's Exynos 4412 or 4210 processor.

Samsung has yet to respond to our request for comment, but it's likely that it will roll out an update to fix the problem soon. Until then, there's a quick fix available here. Merry Christmas and you're welcome. µ
