Subject: CVE-2018-20191 QEMU: pvrdma: uar_read leads to NULL dereference
Hello,
A Null pointer dereference issue was found in QEMU's implementation of
VMWare's paravirtual RDMA device. It could occur while performing UAR read
operation, as it did not define a routine to handle it.
A guest user/process could use this flaw to crash QEMU process on host,
resulting in DoS.

Thank you.
