these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

Alternatively, you can install these updates by running:

DESCRIPTION

* CVE-2020-12888: Denial-of-service when accessing PCI memory through VFIO.

The VFIO PCI driver can allow users to access disabled PCI memory
regions in certain scenarios, which can lead to a system crash on
some platforms.  This flaw could be exploited by a local attacker
to cause a denial-of-service both directly from the host via a
userspace device driver, or from a guest VM that uses VFIO passthrough.
