CVE-2009-3228 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3228):
  The tc_fill_tclass function in net/sched/sch_api.c in the tc
  subsystem in the Linux kernel 2.4.x before 2.4.37.6 and 2.6.x before
  2.6.31-rc9 does not initialize certain (1) tcm__pad1 and (2)
  tcm__pad2 structure members, which might allow local users to obtain
  sensitive information from kernel memory via unspecified vectors.
