This issue was patched in ELSA-2015-0323.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libvirt-daemon-driver-nodedev package and not the libvirt-daemon-driver-nodedev package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

The (1) qemuDomainMigratePerform and (2) qemuDomainMigrateFinish2 functions in qemu/qemu_driver.c in libvirt do not unlock the domain when an ACL check fails, which allow local users to cause a denial of service via unspecified vectors.
