A flaw was found in the QEMU implementation of VMWare’s paravirtual RDMA device. The issue occurs while handling a “PVRDMA_CMD_CREATE_MR” command due to improper memory remapping (mremap). This flaw allows a malicious guest to crash the QEMU process on the host. The highest threat from this vulnerability is to system availability.
