Security experts from Aleph Research Motorola have discovered a critical kernel command line injection flaw in the Motorola handsets Moto G4 and Moto G5 models. The flaw affects also handsets running the latest Motorola Android bootloader and could be exploited by a local malicious application to execute arbitrary code on the mobile device. The same flaw was found in the Nexus 6 Motorola bootloader, Google fixed it last month. The vulnerability does not lead to a factory reset hence user data remains intact (and still encrypted)”]
