Red Hat Security Advisory

Synopsis: Important: kernel security, bug fix, and enhancement update
Advisory ID: RHSA-2019:1946-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2019:1946
Issue date: 2019-07-30
CVE Names: CVE-2017-12154 CVE-2017-15129 CVE-2017-15274
CVE-2018-3693 CVE-2018-14633
=====================================================================

1. Summary:

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

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):

* An industry-wide issue was found in the way many modern microprocessor
designs have implemented speculative execution of instructions past bounds
check. The flaw relies on the presence of a precisely-defined instruction
sequence in the privileged code and the fact that memory writes occur to an
address which depends on the untrusted value. Such writes cause an update
into the microprocessor’s data cache even for speculatively executed
instructions that never actually commit (retire). As a result, an
unprivileged attacker could use this flaw to influence speculative
execution and/or read privileged memory by conducting targeted cache
side-channel attacks. (CVE-2018-3693)

* Kernel: kvm: nVMX: L2 guest could access hardware(L0) CR8 register
(CVE-2017-12154)

* kernel: net: double-free and memory corruption in get_net_ns_by_id()
(CVE-2017-15129)

* kernel: dereferencing NULL payload with nonzero length (CVE-2017-15274)

* kernel: stack-based buffer overflow in chap_server_compute_md5() in iscsi
target (CVE-2018-14633)

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):

* ovl_create can return positive retval and crash the host (BZ#1696290)

* THP: Race between MADV_DONTNEED and NUMA hinting node migration code
(BZ#1698105)

* RHEL7.6 – Kernel changes for count cache flush Spectre v2 mitigation
(BZ#1708543)

* Poor system performance from thundering herd of kworkers competing for
mddev->flush_bio ownership (BZ#1712762)

* [RHEL7.7] RAID1 `write-behind` causes a kernel panic (BZ#1712999)

Enhancement(s):

* [Intel 7.5 FEAT] i40evf – Update to latest upstream driver version
(BZ#1722774)

* [netdrv] i40e/i40evf: Fix use after free in Rx cleanup path [7.4.z]
(BZ#1723831)

Users of kernel are advised to upgrade to these updated packages, which fix
these bugs and add these enhancements.
