• 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)
