Red Hat Security Advisory

Synopsis: Important: kernel security and bug fix update
Advisory ID: RHSA-2017:0270-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2017-0270.html
Issue date: 2017-02-15
CVE Names: CVE-2016-7117
=====================================================================

1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 7.1
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. 7.1) – noarch, x86_64
Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.1) – x86_64
Red Hat Enterprise Linux Server EUS (v. 7.1) – noarch, ppc64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 7.1) – ppc64, ppc64le, s390x, x86_64

3. Description:

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

Security Fix(es):

* A use-after-free vulnerability was found in the kernel’s socket recvmmsg
subsystem. This may allow remote attackers to corrupt memory and may allow
execution of arbitrary code. This corruption takes place during the error
handling routines within __sys_recvmmsg() function. (CVE-2016-7117,
Important)

Bug Fix(es):

* Previously, an XFS corruption in some cases occurred on Seagate 8TB drive
based volumes after a planned system shutdown or reboot, when a disk write
back cache was used. With this update, the megaraid_sas driver has been
fixed and the XFS corruption no longer occurs in the described scenario.
(BZ#1398177)

* Previously, booting a kdump kernel in some cases failed with this error:

Kernel panic – not syncing: Watchdog detected hard LOCKUP on CPU 0.

This update ensures that the hpet timer software counters, including
hpet_default_delta and hpet_t1_cmp, are initialized before an interrupt
request is registered, and the kdump kernel now boots without the mentioned
error message. (BZ#1404180)

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/):

1382268 – CVE-2016-7117 kernel: Use-after-free in the recvmmsg exit path
