  qemu-kvm built with the USB EHCI Emulation support is vulnerable
  to a memory leakage issue. It could occur while processing packet
  data in ehci_init_transfer. A guest user/process could use this
  issue to leak host memory, resulting in DoS for a host.

  CVE-2016-9922
  qemu-kvm built with the Cirrus CLGD 54xx VGA Emulator support is
  vulnerable to a divide by zero issue. It could occur while copying
