CVE-2010-4655 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-4655):
  net/core/ethtool.c in the Linux kernel before 2.6.36 does not initialize
  certain data structures, which allows local users to obtain potentially
  sensitive information from kernel heap memory by leveraging the
  CAP_NET_ADMIN capability for an ethtool ioctl call.
