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. 8.1) - aarch64, ppc64le, x86_64
Red Hat Enterprise Linux BaseOS EUS (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: net: bluetooth: type confusion while processing AMP packets
(CVE-2020-12351)

* kernel: net: bluetooth: information leak when processing certain AMP
packets (CVE-2020-12352)

* kernel: metadata validator in XFS may cause an inode with a valid,
user-creatable extended attribute to be flagged as corrupt (CVE-2020-14385)

* kernel: memory corruption in net/packet/af_packet.c leads to elevation of
privilege (CVE-2020-14386)

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):

* NFS client autodisconnect timer may fire immediately after TCP connection
setup and may cause DoS type reconnect problem in complex network
environments (BZ#1873571)

* hang on full fs from trace_cmd (BZ#1875789)

* Secure boot key is not loaded with kernel-4.18.0-232.el8.x86_64 /

* [RHEL-8.3] Kdump failed to start when secure boot enabled:
kexec_file_load failed: Required key not available (BZ#1877529)

* [RHEL-8.3] Kdump/kexec kernel panicked on EFI boot: general protection
fault: 0000 [#1] SMP PTI (BZ#1879987)

* [conntrack] udp packet reverse NAT occasionally fail when race condition
request combination with the DNAT load balancing rules (BZ#1882096)

* [Regression] RHEL8.3 Beta - Do not initiate shutdown for
EPOW_SHUTDOWN_ON_UPS event (BZ#1882244)
