Subject: CVE-2018-20126 QEMU: pvrdma: memory leakage when creating cq/qp
Hello,
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.
Upstream patch:

This issue was reported by Li Qiang.
Thank you.
