Samsung Exynos 4 processor powered devices found vulnerable

Samsung Exynos 4 processor operated devices were reported to be vulnerable to attacks from malicious applications according to a developer. The international models of the Galaxy S2 and S3, Galaxy Note and Note 2, Galaxy Tab 7.7 and Galaxy Note 10.1 are among the devices from Samsung running an Exynos 4210 or 4412 processor.

Various devices from Meizu, Lenovo, and smaller Asian manufacturers operating on Exynos 4 processors are also open to attacks. The security risk was discovered and explained by an XDA member, who operates with the handle, ‘alephzain’. The threat will allow the applications to extract data from the device’s RAM and introduce malicious code in the kernel.

Galaxy S3 users faced another problem earlier when a hack code for the device surfaced on the internet. Applications can gain root access to the affected device without any user notification and cause instability in the smartphone’s software. Talking about the threat to Exynos 4 devices, alephzain wrote, “The good news is we can easily obtain root on these devices and the bad is there is no control over it.”

Another XDA member, ‘chainfire’ has released an APK, which roots the affected device and removes the vulnerability and if the device is not rooted, then the application roots it. It is cautioned that the usage of the patch will void the users’ warranty of the device.

Samsung has been notified about the vulnerability, but the South Korean company is yet to make an announcement about a fix for the threat. With security issues popping up, Samsung might need to find a permanent fix for the problems in the future.
