Issue date: 2019-02-26
CVE Names: CVE-2018-10902
=====================================================================

1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 6.

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 Desktop (v. 6) – i386, noarch, x86_64
Red Hat Enterprise Linux Desktop Optional (v. 6) – i386, x86_64
Red Hat Enterprise Linux HPC Node (v. 6) – noarch, x86_64
Red Hat Enterprise Linux HPC Node Optional (v. 6) – x86_64
Red Hat Enterprise Linux Server (v. 6) – i386, noarch, ppc64, s390x, x86_64
Red Hat Enterprise Linux Server Optional (v. 6) – i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 6) – i386, noarch, x86_64
Red Hat Enterprise Linux Workstation Optional (v. 6) – i386, x86_64

3. Description:

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

Security Fix(es):

* kernel: MIDI driver race condition leads to a double-free
(CVE-2018-10902)

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):

* Previously backported upstream patch caused a change in the behavior of
page fault handler. As a consequence, applications compiled through GNU
Compiler Collection (GCC) version 4.4.7 sometimes generated stack access
exceeding the 64K limit. Running such applications subsequently triggered a
segmentation fault. With this update, the 64k limit check in the page fault
handler has been removed. As a result, running the affected applications no
longer triggers the segmentation fault in the described scenario.

Note that removing the limit check does not impact the integrity of the
kernel itself. (BZ#1644401)

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.

5. Bugs fixed (https://bugzilla.redhat.com/):

1590720 – CVE-2018-10902 kernel: MIDI driver race condition leads to a double-free
