Alexander Bulekov discovered that QEMU incorrectly handled SDHCI device
emulation. An attacker inside the guest could use this issue to cause QEMU
to crash, resulting in a denial of service, or possibly execute arbitrary
code on the host. In the default installation, when QEMU is used with
libvirt, attackers would be isolated by the libvirt AppArmor profile.
