Samsung’s Exynos 4 quad-core mobile processor has a major flaw that can be exploited by hackers to take control of the device, according to a developer who has revealed this at the XDA Forum. According to the developer, this exploit can be manipulated to get the root level access and super user permission on the device. Basically, if a malware loaded app runs on the Exynos 4 device, then the hacker can gain complete control over the device.
