Using Rowhammer bitflips to root Android phones is now a thing

Previously, some experts believed Rowhammer attacks that altered specific pieces of security-sensitive data weren't reliable enough to pose a viable threat because exploits depended on chance hardware faults or advanced memory-management features that could be easily adapted to repel the attacks. Now, an international team of academic researchers is challenging those assumptions by demonstrating a Rowhammer exploit that alters crucial bits of data in a way that completely roots name brand Android devices from LG, Motorola, Samsung, OnePlus, and possibly other manufacturers. An app containing the researchers' rooting exploit requires no user permissions and doesn't rely on any vulnerability in Android to work.
