CVE-2009-0834 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-0834):
  The audit_syscall_entry function in the Linux kernel 2.6.28.7 and
  earlier on the x86_64 platform does not properly handle (1) a 32-bit
  process making a 64-bit syscall or (2) a 64-bit process making a
  32-bit syscall, which allows local users to bypass certain syscall
  audit configurations via crafted syscalls, a related issue to
  CVE-2009-0342 and CVE-2009-0343.
