CVE-2009-2584 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-2584):
  Off-by-one error in the options_write function in
  drivers/misc/sgi-gru/gruprocfs.c in the SGI GRU driver in the Linux
  kernel 2.6.30.2 and earlier on ia64 and x86 platforms might allow
  local users to overwrite arbitrary memory locations and gain
  privileges via a crafted count argument, which triggers a stack-based
  buffer overflow.
