Synopsis:          Important: kernel security and bug fix update
Advisory ID:       RHSA-2022:5220-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2022:5220
Issue date:        2022-06-28
CVE Names:         CVE-2020-29368 CVE-2022-1012 CVE-2022-1729

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

1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 8.2
Extended Update Support.

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 EUS (v. 8.2) - aarch64, ppc64le, x86_64
Red Hat Enterprise Linux BaseOS EUS (v. 8.2) - 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)

* kernel: the copy-on-write implementation can grant unintended write
access because of a race condition in a THP mapcount check (CVE-2020-29368)

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):

* slub corruption during  LPM of hnv interface (BZ#2081252)

* sleeping function called from invalid context at
kernel/locking/spinlock_rt.c:35 (BZ#2082090)

* Backport request of "genirq: use rcu in kstat_irqs_usr()" (BZ#2083310)

* kernel memory leak while freeing nested actions (BZ#2086604)

* dm: sync rhel-8.6 with upstream 5.13 through 5.16 fixes and improvements
(BZ#2088036)

* NFS processing deadlock in  low memory condition (BZ#2094459)

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.
