====================================================================
1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 8.1
Update Services for SAP Solutions.

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 BaseOS E4S (v. 8.1) - aarch64, noarch, ppc64le, s390x, x86_64

3. Description:

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

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-2022-32250)

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):

* Backport request of "genirq: use rcu in kstat_irqs_usr()" (BZ#2083311)

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/):

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
