"An update for kernel-rt is now available for Red Hat Enterprise Linux
7.

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.

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: buffer overflow in cfg80211_mgd_wext_giwessid in
net/wireless/ wext-sme.c (CVE-2019-17133)

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

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) :

* patchset for x86/atomic: Fix smp_mb__{before,after}_atomic()
[kernel-rt] (BZ#1772522)

* kernel-rt: update to the RHEL7.7.z batch#4 source tree (BZ#1780322)

* kvm nx_huge_pages_recovery_ratio=0 is needed to meet KVM-RT low
latency requirement (BZ#1781157)

* kernel-rt: hard lockup panic in during execution of CFS bandwidth
period timer (BZ#1788057)

This plugin has been deprecated. Although RHSA-2020:0375 exists, it is
for kernel-rt, which does not exist on CentOS. This CentOS copy of the
advisory duplicates the CVEs and packages from the non-rt kernel in
RHSA-2020:0374."
