The mm subsystem in the Linux kernel through 3.2 does not properly enforce
the CONFIG_STRICT_DEVMEM protection mechanism, which allows local users to
read or write to kernel memory locations in the first megabyte (and bypass
slab-allocation access restrictions) via an application that opens the
/dev/mem file, related to arch/x86/mm/init.c and drivers/char/mem.c.
