qemu-kvm-rhev is vulnerable to denial of service (DoS) attacks. The vulnerability exists as a memory leak in hw/watchdog/wdt_i6300esb.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (host memory consumption and QEMU process crash) via a large number of device unplug operations.
