CVE-2013-4511 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-4511):
  Multiple integer overflows in Alchemy LCD frame-buffer drivers in the Linux
  kernel before 3.12 allow local users to create a read-write memory mapping
  for the entirety of kernel memory, and consequently gain privileges, via
  crafted mmap operations, related to the (1) au1100fb_fb_mmap function in
  drivers/video/au1100fb.c and the (2) au1200fb_fb_mmap function in
  drivers/video/au1200fb.c.
