DESCRIPTION
* CVE-2020-16166: Confidentiality vulnerability in the generation of the
device ID.
A flaw in the generation of the device ID from the network RNG could
result in a potential issue allowing remote attackers to make
observations that help to obtain sensitive information about
the internal state of the network RNG and compromise the data
confidentiality.

* Guest VM leaks bits into host control register, causing host to panic.
In the event that a guest VM schedules out during a machine check error,
the host's XCR0 register may get populated with incorrect values. This
will cause a general protection fault on the host, leading to a
denial-of-service.
