Language:

Synopsis

The remote Red Hat host is missing one or more security updates for kernel.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:0204 advisory.

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

Security Fix(es):

* 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 mwifiex_uap_parse_tail_ies function in drivers/net/wireless/marvell/mwifiex/ie.c (CVE-2019-10126)

* kernel: heap overflow in mwifiex_update_vs_ie() function of Marvell WiFi driver (CVE-2019-14816)

* Kernel: KVM: OOB memory access via mmio ring buffer (CVE-2019-14821)

* 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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL kernel package based on the guidance in RHSA-2020:0204.
