INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack running Ubuntu 16.04
Xenial install these updates.
On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

Alternatively, you can install these updates by running:
# /usr/sbin/uptrack-upgrade -y
DESCRIPTION
* Use-after-free when writing to SLIP serial line.
A locking error when writing to SLIP serial line while the line is being
closed could lead to a use-after-free. A local attacker could use this
flaw to cause a denial-of-service.
* CVE-2020-2732: Privilege escalation in Intel KVM nested emulation.
Incorrect handling of emulated instructions and IO bitmaps could allow
an unprivileged user in a nested KVM guest instance to crash the system
or potentially, escalate privileges.
