  Off-by-one error in the iov_iter_advance function in mm/filemap.c in the
  Linux kernel before 2.6.27-rc2 allows local users to cause a denial of
  service (system crash) via a certain sequence of file I/O operations with
  readv and writev, as demonstrated by testcases/kernel/fs/ftest/ftest03 from
  the Linux Test Project.
