Advisory ID:       RHSA-2022:5249-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2022:5249
Issue date:        2022-06-28
CVE Names:         CVE-2022-1012 CVE-2022-1729 CVE-2022-1966
                   CVE-2022-27666
====================================================================
1. Summary:

An update for kernel 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 CodeReady Linux Builder (v. 9) - aarch64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux AppStream (v. 9) - aarch64, noarch, ppc64le, s390x, x86_64
Red Hat Enterprise Linux BaseOS (v. 9) - 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-2022-1966)

* 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):

* make SHA512_arch algos and CRYPTO_USER built-ins (BZ#2072643)

* SR-IOV performance > 50% degradation (BZ#2074830)

* fix data corruption caused by dm-integrity (BZ#2082187)

* SCTP client-side peeloff issues [rhel-9] (BZ#2084044)

* TCP connection fails in a asymmetric routing situation (BZ#2085480)

* Fails to boot Multiple RT VMs each with multiple vCPUs (BZ#2086963)

* spec: Fix separate tools build (BZ#2090852)

* call traces related to eeh_pseries observed and vmcore is not captured,
when kdump is triggered (BZ#2092255)

* Mark ThunderX NIC driver as unmaintained (BZ#2092638)

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.
