An XDA Developers forum member has created an exploit that obtains root privileges and enables malicious application installation on many Samsung devices. The exploit can root any Exynos 4210 or 4412 processor without requiring an Odin flash that most similar root exploits require, according to XDA s Joseph Hindy. The list of devices that use the affected processors includes the Samsung Galaxy S II, Samsung Galaxy Tab 7.0 Plus, Galaxy Note II, and Meizu MX 2-Core.
