INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running UEKR4 4.1.12 on
OL6 and OL7 install these updates.

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

DESCRIPTION

* Denial-of-service when rebooting guests using Intel I40e Ethernet driver.

A logic error when setting interrupt affinity in Intel I40e Ethernet
driver could lead to a host kernel crash when rebooting guest VM. An
attacker with capability to reboot guest VM could use this flaw to
cause a denial-of-service.
