=====================================================================

1. Summary:

An update for kernel-rt is now available for Red Hat Enterprise Linux 9.

Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Real Time (v. 9) - x86_64
Red Hat Enterprise Linux Real Time for NFV (v. 9) - x86_64

3. Description:

The kernel-rt packages provide the Real Time Linux Kernel, which enables
fine-tuning for systems with extremely high determinism requirements.

Security Fix(es):

* kernel: Small table perturb size in the TCP source port generation
algorithm can lead to information leak (CVE-2022-1012)

* kernel: race condition in perf_event_open leads to privilege escalation
(CVE-2022-1729)

* kernel: a use-after-free write in the netfilter subsystem can lead to
privilege escalation to root (CVE-2022-1966)

* kernel: buffer overflow in IPsec ESP transformation code (CVE-2022-27666)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.

Bug Fix(es):

* kernel-rt: update RT source tree to the latest RHEL-9.0.z1 Batch
(BZ#2089492)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

The system must be rebooted for this update to take effect.

5. Bugs fixed (https://bugzilla.redhat.com/):

2061633 - CVE-2022-27666 kernel: buffer overflow in IPsec ESP transformation code
2064604 - CVE-2022-1012 kernel: Small table perturb size in the TCP source port generation algorithm can lead to information leak
2086753 - CVE-2022-1729 kernel: race condition in perf_event_open leads to privilege escalation
2092427 - CVE-2022-1966 kernel: a use-after-free write in the netfilter subsystem can lead to privilege escalation to root
