No.  It is part of RHEL6.5.  My understanding is the kernel part should
work with RHEL6.4, but it will break the RHEL6.4 pam_tty_audit module of
pam (which needs to be updated anyways to get the new feature to work).
I can't speak to the ease of upgrading pam to the RHEL6.5 version while
still running essentially a RHEL6.4 system.
