[Ksplice][EL8-Updates] New Ksplice updates for OL 8 and RHEL 8 (RHSA-2020:3016)

[Alex Thorlton]

Synopsis: RHSA-2020:3016 can now be patched using Ksplice
CVEs: CVE-2020-12888

Systems running RHCK on Oracle Linux 8 and Red Hat Enterprise Linux 8
can now use Ksplice to patch against the latest Red Hat Security
Advisory, RHSA-2020:3016.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running OL 8 and RHEL 8
install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


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.
