CVE-2009-4141 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-4141):
  Use-after-free vulnerability in the fasync_helper function in
  fs/fcntl.c in the Linux kernel before 2.6.33-rc4-git1 allows local
  users to gain privileges via vectors that include enabling O_ASYNC
  (aka FASYNC or FIOASYNC) on a locked file, and then closing this file.
