Subject: CVE-2018-20123 QEMU: pvrdma: memory leakage in device hotplug
Hello,
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.
Upstream patch:
