Description Prasad J Pandit 2018-12-19 07:13:47 UTC
An infinite loop issue was found in QEMU's implementation of
VMWare's paravirtual RDMA device. It could occur while transferring
QP ring objects' data in pvrdma_qp_send/recv functions.

A guest user/process could use this flaw to cause infinite loop resulting in DoS.
