– Security researchers have demonstrated how to gain root privileges from a normal Android app without relying on any software bug.The unprivileged application is able to gain full administrative permissions by exploiting the Rowhammer vulnerability present in modern RAM chips.Essentially, malicious code can change the content of memory it should never be able to access.

– Researchers have devised an attack that gains unfettered “root” access to a large number of Android phones, exploiting a relatively new type of bug that allows adversaries to manipulate data stored in memory chips.The breakthrough has the potential to make millions of Android phones vulnerable, at least until a security fix is available, to a new form of attack that seizes control of core parts of the operating system and neuters key security defenses.Equally important, it demonstrates that the new class of exploit, dubbed Rowhammer, can have malicious and far-reaching effects on a much wider number of devices than was previously known, including those running ARM chips.
