====================================================================
1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 7.4
Extended Update Support.

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux ComputeNode EUS (v. 7.4) - noarch, x86_64
Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.4) - x86_64
Red Hat Enterprise Linux Server EUS (v. 7.4) - noarch, ppc64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 7.4) - ppc64, ppc64le, x86_64

3. Description:

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

Security Fix(es):

* kernel: Memory corruption due to incorrect socket cloning (CVE-2018-9568)

* kernel: Missing check in fs/inode.c:inode_init_owner() does not clear
SGID bit on non-directories for non-members (CVE-2018-13405)

* kernel: nfs: use-after-free in svc_process_common() (CVE-2018-16884)

* kernel: nfs: NULL pointer dereference due to an anomalized NFS message
sequence (CVE-2018-16871)

* kernel: hw: Spectre SWAPGS gadget vulnerability (CVE-2019-1125)

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):

* fragmented packets timing out (BZ#1729411)

* kernel build: speed up debuginfo extraction (BZ#1731462)

* TCP packets are segmented when sent to the VM (TAP) (BZ#1732744)

* TCP packets are segmented when sent to the VLAN device when coming from
VXLAN dev. (BZ#1732809)

* skb head copy occurs when sending traffic over OVS managed VXLAN tunnel
(BZ#1733626)

* [mlx4] VXLAN over VLAN TCP segmentation (BZ#1734160)

* use "make -jN" for modules_install (BZ#1735081)

* shmem: consider shm_mnt as a long-term mount (BZ#1737376)

* [ESXi][RHEL7]use-after-free of scsi_cmnd on VMWare virtual guest with
vmw_pvscsi and ata_piix (BZ#1737377)

* Backport TCP follow-up for small buffers (BZ#1739127)

4. Solution:
