Various Samsung smartphone models are affected with a security vulnerability that could grant apps access to sensitive user information and leave handsets at risk of bricking and malware attacks, according to one software developer.
As explained by XDA forum user \”alephzain,\” the vulnerability resides in the Android kernel of Samsung devices powered by Exynos 4, the ARM-based processor found in many of the company\’s smartphones and tablets.
The security hole provides an easier way for users to root their handsets, but in the process gives apps full read-write permissions. Having those could give apps full control of the device, which allows them to have complete access to the system\’s physical memory and potentially introduce malware to the handset.
Alephzain says that the Samsung Galaxy S II, Galaxy Note II, Meizu MX, and \”potentialy all devices who embed Exynos processor (4210 and 4412) which use Samsung kernel sources\” could be affected. Devices using the Exynos 5 chip, however, appear to be in the clear.
Samsung has yet to announce any fix for the vulnerability, although with it potentially affecting some of the company\’s most popular devices, one would expect some sort of patch to be on the way soon.
