The kernel in Samsung Galaxy S2, Galaxy Note 2, MEIZU MX, and possibly
other Android devices, when running an Exynos 4210 or 4412 processor, uses
weak permissions (0666) for /dev/exynos-mem, which allows attackers to read
or write arbitrary physical memory and gain privileges via a crafted
application, as demonstrated by ExynosAbuse.

Notes
