* hw: Machine Check Error on Page Size Change (IFU) (CVE-2018-12207)

* hw: TSX Transaction Asynchronous Abort (TAA) (CVE-2019-11135)

* kernel: nfs: use-after-free in svc_process_common() (CVE-2018-16884)

* hw: Intel GPU blitter manipulation can allow for arbitrary kernel memory
write (CVE-2019-0155)

* Kernel: vhost_net: infinite loop while receiving packets leads to DoS
(CVE-2019-3900)

* Kernel: page cache side channel attacks (CVE-2019-5489)

* hardware: bluetooth: BR/EDR encryption key negotiation attacks (KNOB)
(CVE-2019-9506)

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

* hw: Intel GPU Denial Of Service while accessing MMIO in lower power state
(CVE-2019-0154)

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):

* Backport TCP follow-up for small buffers (BZ#1739184)

* TCP performance regression after CVE-2019-11478 bug fix (BZ#1743170)

* RHEL8.0 – bnx2x link down, caused by transmit timeouts during load test
(Marvell/Cavium/QLogic) (L3:) (BZ#1743548)

* block: blk-mq improvement (BZ#1780567)

* RHEL8.0 – Regression to RHEL7.6 by changing force_latency found during
RHEL8.0 validation for SAP HANA on POWER (BZ#1781111)

* blk-mq: overwirte performance drops on real MQ device (BZ#1782183)

* RHEL8: creating vport takes lot of memory i.e 2GB per vport which leads
to drain out system memory quickly. (BZ#1782705)
