The owners of a Samsung Galaxy Note I and II phablet and Galaxy Note 10.1, Tab 7.0 Plus, Tab 7.7 tablets and other tablets that use 4412 and 4210 processors you have to take this as bad news. It seems that Quad and Dual Core Exynos SoCs named have a hole in your security That makes them able to be controlled from an external device if we installed an application of that style. That is why many smartphones of the Korean company are also at risk, including the SII and the SIII. This is stated by the guys at XDA-Developers and, said like that, it is really shocking.
One of its developers opened a thread on their forum, which you can access by this link, and it warned that it had been able to root a Samsung SIII without having to flash it with Odin. What might seem like a good thing at first, actually means that if you install a malicious application, capable of stealing your data or controlling your device remotely, it could enter your computer in a much easier way. The fault is located in the kernel.
Samsung has been informed of this problem and, although it has not yet commented on it, it is sure that it is already working on a solution. This happens according to XDA by an update of your software that plugs the hole, but it may take time to arrive.
Meanwhile they themselves offer a solution in the form of a typical application patch. Its design is due to one of the most prestigious members of the developer community, Chainfire, which you can download in the following link.
There is another option to alleviate the matter until an official solution that people from the Project voodoo and that no need to be root and it is also reversible. You can get it in this link to a post of his websites.
We recommend that you read the information in the two links that we have recommended well, since it may be modified until you read this. We would also like to warn you that this is not an official solution and that you take responsibility for what may happen to your team.
Another option is to do nothing until the update arrives and try not to install apps from unknown sources in the meantime.
