CVE-2010-1643 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-1643):
  mm/shmem.c in the Linux kernel before 2.6.28-rc3, when strict
  overcommit is enabled, does not properly handle the export of shmemfs
  objects by knfsd, which allows attackers to cause a denial of service
  (NULL pointer dereference and knfsd crash) or possibly have
  unspecified other impact via unknown vectors.
