INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running UEKR5 4.14.35
on OL7 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-2022-3028: Out-of-bounds memory access in IP framework XFRM subsystem.

A race condition can occur when multiple calls to the same function
in the IP framework can lead to a race condition, and subsequent
out-of-bounds memory accesses. A local attacker could exploit this flaw
to leak kernel memory, or make arbitrary writes to kernel memory.

Orabug: 34566753

* Reset CR4 during kexec load.

A failure to reset the CR4 register when kexec loads a new kernel can
lead to kexec boot failures.

Orabug: 34617675

* Note: Oracle will not be providing an update for CVE-2022-36123.

This CVE is only applicable at boot time, so by the time Ksplice live updates
are applied, the relevant code has already ran.

SUPPORT

Ksplice support is available at ksplice-support_ww@oracle.com.
