CVE-2018-20123 QEMU: pvrdma: memory leakage in device hotplug
A memory leakage issue was found in the way QEMU initialised its
VMWare's paravirtual RDMA device. In pvrdma_realize() routine, if
an error occurred, it did not release memory resources allocated
to various objects.
A guest user/process could use this flaw to leak host memory,
resulting in DoS for host.
