Serious Security Flaws Found On Exynos Based Samsung Galaxy Devices

 

A major security flaw has been found on devices using Exynos 4 processor and Samsung Kernel sources. The flaw was detected by a member of XDA-Developers’ forum. The security flaw was actually found on the kernel which grants all users and apps Read/Write permissions and allow access to full Physical Memory. So, all Exynos 4 devices come pre-rooted. For those who don’t know what rooting is, Rooting is a process of gaining access to device resources which are typically denied to users, mainly due to security reasons.

So do we have to be scared? Well, to a certain extent, yes, since this flaw could give unrestricted access to malwares. So we advise you to take precautions while installing apps on your device, especially from third party sources. Malwares can easily steal secure information from your device and leave your device unusable.

On the other hand, this flaw might come as a good news for developers and gadget freaks. Since the devices can now be easily rooted, you can install new updates and new versions of the OS without flashing your device. An app is already out which exploits with vulnerability, called ExynosAbuse, which lets you root the device with just a single click of a button. Developers now can easily access resources which were earlier restricted.

So it is a sort of a good news – bad news thing, depending on your point of view. So are you thinking if your device is one of those which are affected? To answer that, here is a list of devices which have been affected:
