CVE-2011-1076 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1076):
  net/dns_resolver/dns_key.c in the Linux kernel before 2.6.38 allows remote
  DNS servers to cause a denial of service (NULL pointer dereference and OOPS)
  by not providing a valid response to a DNS query, as demonstrated by an
  erroneous grand.centrall.org query, which triggers improper handling of
  error data within a DNS resolver key.
