Yesterday, the folks over at XDA Developers found a major vulnerability flaw within the Samsung Exynos 4210 and 4412 chips. The flaw gives users access to all of the physical memory of the device, which in ways is both beneficial and detrimental to devices containing those chips.
The good news is that devices containing those chips will be super easy to root. The bad news is that those devices are fully exposed to potential malicious apps.
Obviously the con greatly outweighs the pro of this situation. Any app can gain root access to the device without any user alerts or need to restart the device.
A prominent XDA member, Chainfire, has created an APK that will both root the devices and patch the vulnerability flaw. Root isn’t required, but be aware that this will potentially void your warranty. That may be a risk many of you are willing to take in order to ensure the safety of your device and personal information.
The list of devices running the Exynos 4210 & 4412 processors include:
- International Samsung Galaxy SII
- International Samsung Galaxy SIII
- Samsung Galaxy Note
- Samsung Galaxy Note II
- Samsung Galaxy Tab 7.7
- Samsung Galaxy Note 10.1
- Various devices from Meizu, Lenovo, and smaller asian manufacturers
Those with the U.S. variant of the Samsung Galaxy SIII do not have to worry about this security flaw.
Samsung commented on the vulnerability flaw, saying that they are “currently in the process of conducting an internal review”. They’re vague about what they plan on doing, but at least they’re aware of their issue. You can expect a fix or a patch in the near future.
