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

1. Summary:

An update for kernel-rt 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 Enterprise Linux Real Time (v. 8) – x86_64
Red Hat Enterprise Linux Real Time for NFV (v. 8) – x86_64

3. Description:

The kernel-rt packages provide the Real Time Linux Kernel, which enables
fine-tuning for systems with extremely high determinism requirements.

Security Fix(es):

* kernel: heap overflow in mwifiex_update_vs_ie() function of Marvell WiFi
driver (CVE-2019-14816)

* kernel: heap-based buffer overflow in mwifiex_process_country_ie()
function in drivers/net/wireless/marvell/mwifiex/sta_ioctl.c
(CVE-2019-14895)

* kernel: heap overflow in marvell/mwifiex/tdls.c (CVE-2019-14901)

* kernel: rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in
the Linux kernel lacks a certain upper-bound check, leading to a buffer
overflow (CVE-2019-17666)

* kernel: heap overflow in mwifiex_set_uap_rates() function of Marvell Wifi
Driver leading to DoS (CVE-2019-14814)

* kernel: heap-overflow in mwifiex_set_wmm_params() function of Marvell
WiFi driver leading to DoS (CVE-2019-14815)

* kernel: incomplete fix for race condition between
mmget_not_zero()/get_task_mm() and core dumping in CVE-2019-11599
(CVE-2019-14898)

* Kernel: KVM: export MSR_IA32_TSX_CTRL to guest – incomplete fix for TAA
(CVE-2019-11135) (CVE-2019-19338)

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):

* kernel-rt: update RT source tree to the RHEL-8.1.z2 source tree
(BZ#1780326)

4. Solution:
