====================================================================
1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 8.0
Update Services for SAP Solutions.

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 Enterprise Linux BaseOS E4S (v. 8.0) - 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: kernel: DAX hugepages not considered during mremap
(CVE-2020-10757)

* kernel: Rogue cross-process SSBD shutdown. Linux scheduler logical bug
allows an attacker to turn off the SSBD protection. (CVE-2020-10766)

* kernel: Indirect Branch Prediction Barrier is force-disabled when STIBP
is unavailable or enhanced IBRS is available. (CVE-2020-10767)

* kernel: Indirect branch speculation can be enabled after it was
force-disabled by the PR_SPEC_FORCE_DISABLE prctl command. (CVE-2020-10768)

* kernel: buffer overflow in mwifiex_cmd_append_vsie_tlv function in
drivers/net/wireless/marvell/mwifiex/scan.c (CVE-2020-12653)

* kernel: heap-based buffer overflow in mwifiex_ret_wmm_get_status function
in drivers/net/wireless/marvell/mwifiex/wmm.c (CVE-2020-12654)

* Kernel: vfio: access to disabled MMIO space of some devices may lead to
DoS scenario (CVE-2020-12888)

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):

* [ESXi][RHEL8.1.0] scsi driver SG list incompatibility (vmw_pvscsi)
(BZ#1839359)

4. Solution:
