XDA Developers forum member alephzain over the weekend shared a new vulnerability affecting the Galaxy S III, Galaxy Note II, Galaxy S II and potentially any Samsung smartphone that uses the Exynos mobile processor.
While determining new ways to root the Galaxy S III, the user discovered the security hole in the kernel that gives anyone full read-write access to all physical memory on the device.
The vulnerability is quite dangerous because it can expose users of these devices to malicious apps on the Play Store that attempt to take advantage of the issue and wreak havoc on an unknowing user. Fortunately, rooting these devices can be quite difficult. Moreover, Samsung is aware of the issue and is ”currently in the process of conducting an internal review” to determine the exact cause of this problem.
