The XDA Developers forums are built with some geniuses at work, where this time a user with the name of 'alephzain' who is claiming that they've discovered a hole in multiple Samsung devices that gives access to all physical memory.
This hole can be used to access devices to remotely wipe them, brick the device, or worse, access user data without the user noticing. Alephzain tested the vulnerability out on a Samsung Galaxy S III to root his device, but noticed that the flaw is also on the Galaxy S II, Galaxy Note II, the Meizu MX and other devices sporting an Exynos 4210 and 4412 processor, using Samsung kernel sources.
Samsung haven't come out and confirmed the vulnerability, but it is already being exploited. The post on the forum notes the following devices are at risk: Samsung Galaxy S2 GT-I9100, Samsung Galaxy S3 GT-I9300, Samsung Galaxy S3 LTE GT-I9305, Samsung Galaxy Note GT-N7000, Samsung Galaxy Note 2 GT-N7100, Verizon Galaxy Note 2 SCH-I605 (with locked bootloaders), Samsung Galaxy Note 10.1 GT-N8000, and the Samsung Galaxy Note 10.1 GT-N8010.
