New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 7.9
Synopsis
The remote Red Hat host is missing one or more security updates.
Description
An update for kernel is now available for Red Hat Enterprise Linux 8.0 Update Services for SAP Solutions.
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 packages contain the Linux kernel, the core of any Linux operating system.

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)
