CVE-2018-20125 [HIGH] CVE-2018-20125 QEMU: pvrdma: null dereference or excessive memory allocation when creating QP/CQ
CVE-2018-20125 QEMU: pvrdma: null dereference or excessive memory allocation when creating QP/CQ
A Null pointer dereference issue was found in QEMU's implementation of
VMWare's paravirtual RDMA device. It could occur while creating CQ/QP
ring objects in pvrdma_ring_init() routine.
A guest user/process could use this flaw to crash QEMU process or
allocate excessive memory on host resulting in DoS.
