1. Summary:

An update for kernel-alt is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact
of Moderate. 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 for ARM and IBM Power LE (POWER9) Server (v. 7) - aarch64, noarch, ppc64le, s390x
Red Hat Enterprise Linux for ARM and IBM Power LE (POWER9) Server Optional (v. 7) - aarch64, noarch, ppc64le

3. Description:

The kernel-alt packages provide the Linux kernel version 4.x.

Security Fix(es):

* kernel: out-of-bounds memcpy in fs/ext4/inline.c:ext4_read_inline_data()
with crafted ext4 image (CVE-2018-11412)

* kernel: use-after-free in jbd2_journal_commit_transaction funtion
(CVE-2018-10876)

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):

* blk-mq IO hang in null_blk test (BZ#1581223)

* lpfc remove lpfc_enable_pbde module parameter. (BZ#1615875)

* RHEL-Alt-7.6 - [Power9][DD2.2][4.14.0-109]package installation segfaults
inside debian chroot env in P9 KVM guest with HTM enabled (kvm)
(BZ#1628817)

* Pegas1.1 - [P9] "threads=2" or higher is required to boot up VM with
above 256 vcpu [rhel-alt-7.6.z] (BZ#1634653)

* RHEL-Alt-7.6 Snapshot5 - System crashed under stress-ng & HTX on the mix
mode guest (kvm) (BZ#1637890)

* RHEL-Alt-7.6 - BostonESS:P9:DD2.01 - Testing Ethtool options 'r' and 'p'
for the i40e driver causes the kernel to crash and reboots the server
(i40e) (CORAL) (BZ#1644606)

* RHEL-Alt-7.6 Host/RHV4.2: system crashed and kdump failed to collect CPUs
in KVM guests (BZ#1649196)

* RHEL-Alt-7.6 Host:BostonLC:P9:boslcp1: system crashed in
__find_linux_pte+0xac (kvm) (BZ#1651065)

* [LLNL 7.7 Bug] Rasdaemon doesn’t seem to collect APEI errors (BZ#1664495)
