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)

(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)
