* kernel: kvm: guest userspace to guest kernel write (CVE-2018-10853)

* kernel: TLB flush happens too late on mremap (CVE-2018-18281)

* 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):

* RHEL 7.7 RC1 - Host crashes about 4.5 hours into switch port bounce test (BZ#1763623)

* [Azure][7.8] Include patch PCI: hv: Avoid use of hv_pci_dev->pci_slot after freeing it (BZ#1766088)

* [Hyper-V][RHEL7.8] When accelerated networking is enabled on RedHat, network interface(eth0) moved to new network namespace does not obtain IP address. (BZ#1766092)

* [Azure][RHEL 7.6] hv_vmbus probe pass-through GPU card failed (BZ#1766096)

* Since RHEL commit 5330f5d09820 high load can cause dm-multipath path failures (BZ#1770112)

* Hard lockup in free_one_page()->_raw_spin_lock() because sosreport command is reading from /proc/pagetypeinfo (BZ#1770731)

* [ESXi][RHEL7]use-after-free of scsi_cmnd on VMWare virtual guest with vmw_pvscsi and ata_piix (BZ#1770737)

* fix compat statfs64() returning EOVERFLOW for when _FILE_OFFSET_BITS=64 (BZ#1775677)

* Kernel experiences panic in update_group_power() due to division error (BZ#1775681)

* Guest crash after load cpuidle-haltpoll driver (BZ#1776288)

* Issues with nova/cinder and attaching disks, /dev/disk/by-id missing some times (BZ#1776291)

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-2020:0179.
