Synopsis:          Important: kernel security and bug fix update
Advisory ID:       RHSA-2021:2168-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2021:2168
Issue date:        2021-06-01
CVE Names:         CVE-2021-3501 CVE-2021-3543 
====================================================================
1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 8.

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. 8) - aarch64, ppc64le, x86_64
Red Hat Enterprise Linux BaseOS (v. 8) - 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: userspace applications can misuse the KVM API to cause a write of
16 bytes at an offset up to 32 GB from vcpu->run (CVE-2021-3501)

* kernel: nitro_enclaves stale file descriptors on failed usercopy
(CVE-2021-3543)

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):

* OVS mistakenly using local IP as tun_dst for VXLAN packets (?)
(BZ#1944667)

* Selinux: The task calling security_set_bools() deadlocks with itself when
it later calls  selinux_audit_rule_match(). (BZ#1945123)

* [mlx5] tc flower mpls match options does not work (BZ#1952061)

* mlx5: missing patches for ct.rel (BZ#1952062)

* CT HWOL: with OVN/OVS, intermittently, load balancer hairpin TCP packets
get dropped for seconds in a row (BZ#1952065)

* [Lenovo 8.3 bug] Blackscreen after clicking on "Settings" icon from
top-right corner. (BZ#1952900)

* RHEL 8.x missing uio upstream fix. (BZ#1952952)

* Turbostat doesn't show any measured data on AMD Milan (BZ#1952987)

* P620 no sound from front headset jack (BZ#1954545)

* RHEL kernel 8.2 and higher are affected by data corruption bug in raid1
arrays using bitmaps. (BZ#1955188)

* [net/sched] connection failed with DNAT + SNAT by tc action ct
(BZ#1956458)

4. Solution:

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