[Ksplice][RHEL9-Updates] New Ksplice updates for RHEL 9 (RHSA-2023:5069)

[Oracle Ksplice]

Synopsis: RHSA-2023:5069 can now be patched using Ksplice
CVEs: CVE-2023-20593 CVE-2023-3610

Systems running Red Hat Enterprise Linux 9 can now use Ksplice to
patch against the latest Red Hat Security Advisory, RHSA-2023:5069.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running RHEL 9 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

* Improved update to CVE-2023-3610: Use-after-free in netfilter module.

A use-after-free vulnerability was found in the netfilter: nf_tables
component in the Linux kernel due to a missing error handling. A local
attacker with CAP_NET_ADMIN capability can use this flaw to get a local
privilege escalation.


* Note: Oracle will not provide a zero-downtime fix for CVE-2023-20593.

The optimal fix for this CVE on the system is a microcode update for
affected CPUs.  Customers will need to upgrade the microcode on
affected CPUs in order to mitigate this vulnerability.
