Integer overflow in the fb_mmap function in drivers/video/fbmem.c in the
Linux kernel before 3.8.9, as used in a certain Motorola build of Android
4.1.2 and other products, allows local users to create a read-write memory
mapping for the entirety of kernel memory, and consequently gain
privileges, via crafted /dev/graphics/fb0 mmap2 system calls, as
demonstrated by the Motochopper pwn program.

Notes

Author Note
sbeattie requires write access to /dev/fb0 and other devices, which is usually on permitted to root and the video group.
