A kernel exploit was recently found by Alephzain. This Root method however will not be accepted with Overwhelming cheers and applause like methods in the past. That is because the exploit that it uses can be used by any app to gain root privileges on your device. Samsung should have a fix for this asap. The root apk itself is not malware as it is completely unmodified but it provides a proof of concept that the exploit does exist. Affected devices include the Sprint Galaxy S 2, International Galaxy S 2, International Galaxy S 3, International Galaxy Note, International and Verizon Galaxy Note 2, and other Exynos 4 devices.
