CVE-2009-0676 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-0676):
  The sock_getsockopt function in net/core/sock.c in the Linux kernel
  before 2.6.28.6 does not initialize a certain structure member, which
  allows local users to obtain potentially sensitive information from
  kernel memory via an SO_BSDCOMPAT getsockopt request.
