Synopsis: Moderate: kernel security and bug fix update
Advisory ID: RHSA-2020:0036-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2020:0036
Issue date: 2020-01-07
CVE Names: CVE-2017-0861 CVE-2017-10661 CVE-2018-10853

=====================================================================

1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 7.5
Extended Update Support.

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 ComputeNode EUS (v. 7.5) - noarch, x86_64
Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.5) - x86_64
Red Hat Enterprise Linux Server EUS (v. 7.5) - noarch, ppc64, ppc64le, s390x,
x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 7.5) - ppc64, ppc64le, x86_64

3. Description:

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

Security Fix(es):

* kernel: Use-after-free in snd_pcm_info function in ALSA subsystem
potentially leads to privilege escalation (CVE-2017-0861)

* kernel: Handling of might_cancel queueing is not properly pretected
against race (CVE-2017-10661)

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

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

* kernel: a NULL pointer dereference in
drivers/scsi/megaraid/megaraid_sas_base.c leading to DoS (CVE-2019-11810)

* kernel: use-after-free in drivers/char/ipmi/ipmi_si_intf.c,
ipmi_si_mem_io.c, ipmi_si_port_io.c (CVE-2019-11811)

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):

* Hard lockup in free_one_page()->_raw_spin_lock() because sosreport
command is reading from /proc/pagetypeinfo (BZ#1770730)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

The system must be rebooted for this update to take effect.
