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

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 Critical. 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.

The following packages have been upgraded to a later upstream version:
kernel (4.18.0). (BZ#2036933)

Security Fix(es):

* kernel: improper initialization of the "flags" member of the new
pipe_buffer (CVE-2022-0847)

* kernel: fget: check that the fd still exists after getting a ref to it
(CVE-2021-4083)

* kernel: possible privileges escalation due to missing TLB flush
(CVE-2022-0330)

* kernel: cgroups v1 release_agent feature may allow privilege escalation
(CVE-2022-0492)

* kernel: failing usercopy allows for use-after-free exploitation
(CVE-2022-22942)

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):

* [Intel 8.3 Bug] ICX Whitley: PCIe - kernel panic with AER-INJECT
(BZ#2040309)

* [ESXi][RHEL8] A task is stuck waiting for the completion of the
vmci_resouce releasing upon the balloon reset. [None8.2.0.z] (BZ#2052200)

4. Solution:

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