Some of the developers over at XDA forums have discovered a very serious security exploit in all Samsung devices powered by the Exynos 4xxx SoC. The exploit can allow a malicious app to easily root gain access to the RAM/physical memory of your device. This can lead to some serious implications including an app stealing all your data, or put your device in an endless reboot.
The list of affected devices include all Samsung devices powered by the Exynos 4 SoC including the Galaxy S2, Galaxy S3, international Galaxy Note, Galaxy Note 2, the Galaxy Tab 7.7 and the Galaxy Note 10.1.
Many of the developers in the Android community have already informed Samsung about the exploit, and the company should hopefully come out with a fix soon.
The plus side of this exploit is that it also allows advanced users to gain root access to their Samsung device without using ODIN. Chainfire, a very renowned Android developer, has already released an APK – ExynosAbsue – that allows owners of affected devices to easily gain root access on their handset.
Supercurio, another popular Android developer, has released an APK that fixes this vulnerability. However, fixing the vulnerability might break the front camera on your device which might be a deal breaker for many.
