CVE-2012-6422
December 18, 2012
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.
