sidechannel information leaks out of microarchitectural buffers, similar
to the previously described 'Microarchitectural Data Sampling' attack.

CVE-2019-18424: An untrusted domain with access to a physical device can
DMA into host memory, leading to privilege escalation. (bsc#1154461).
CVE-2019-18421: A malicious PV guest administrator may have been able to
escalate their privilege to that of the host. (bsc#1154458).
