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 ComputeNode EUS (v. 7.5) - noarch, x86_64
Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.5) - x86_64
Red Hat Enterprise Linux Server EUS (v. 7.5) - noarch, ppc64, ppc64le, s390x, x86_64

3. Description:

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security Fix(es):

* kernel: Use-after-free in __blk_drain_queue() function in
block/blk-core.c (CVE-2018-20856)

* kernel: use-after-free in fs/xfs/xfs_super.c (CVE-2018-20976)

* kernel: insufficient input validation in kernel mode driver in Intel i915
graphics leads to privilege escalation (CVE-2019-11085)

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

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

* 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: fix race condition between mmget_not_zero()/get_task_mm() and
core dumping (CVE-2019-11599)

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):

* [Hyper-V][RHEL7.6]Hyper-V guest waiting indefinitely for RCU callback
when removing a mem cgroup (BZ#1783175)

Enhancement(s):

* Selective backport: perf: Sync with upstream v4.16 (BZ#1782751)
