A memory leakage issue was found in QEMU's implementation of VMWare's paravirtual RDMA device. It could occur while creating CQ/QP ring objects in create_cq/qp() routines, as it did not free ring objects' memory in case of an error. A guest user/process could use this flaw to leak host memory resulting in DoS.
