How to Fix Samsung Exynos 4 Vulnerability Exploit

Just recently, it was discovered that there was a major vulnerability in smartphones and tablets that are powered by a Samsung Exynos 4 SoC processor. Specifically, the Exynos 4210 and the newer Exynos 4412 mobile processors. This is a serious security flaw, even if your phone is not rooted. Why? because the flaw is in the kernel and it can give any app root access/permission without you even knowing it.

The Dangers of Samsung Exynos 4 SoC Security Flaw

If you are new to this kind of stuff then you should be very afraid, specially if your phone contains confidential and sensitive information. Apps can actually gain access to sensitive information, then send it to somebody or do some really nasty stuff on your device without you even knowing it.

Be very careful specially if you are downloading APK apps/games that are outside the Google Play Store. Since most of the APK files, specially the unofficial and cracked versions that are outside of Google Play are already modified, you can’t really be sure if the APK files contains malwares, trojans and unwanted malicious scripts. You can’t be too sure either with apps downloaded from Google Play Store itself.
