CVE-2009-3612 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3612):
  The tcf_fill_node function in net/sched/cls_api.c in the netlink
  subsystem in the Linux kernel 2.6.x before 2.6.32-rc5, and 2.4.37.6
  and earlier, does not initialize a certain tcm__pad2 structure
  member, which might allow local users to obtain sensitive information
  from kernel memory via unspecified vectors.  NOTE: this issue exists
  because of an incomplete fix for CVE-2005-4881.
