Red Hat Security Advisory

 

Synopsis: Moderate: kernel security and bug fix update

Advisory ID: RHSA-2014:1281-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-1281.html

Issue date: 2014-09-22

CVE Names: CVE-2014-3917

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

 

1. Summary:

 

Updated kernel packages that fix one security issue and several bugs are

now available for Red Hat Enterprise Linux 7.

 

Red Hat Product Security has rated this update as having Moderate security

impact. A Common Vulnerability Scoring System (CVSS) base score, which

gives a detailed severity rating, is available from the CVE link in the

References section.

Red Hat Enterprise Linux Workstation Optional (v. 7) - noarch, x86_64

 

3. Description:

 

The kernel packages contain the Linux kernel, the core of any Linux

operating system.

 

* An out-of-bounds memory access flaw was found in the Linux kernel's

system call auditing implementation. On a system with existing audit rules

defined, a local, unprivileged user could use this flaw to leak kernel

memory to user space or, potentially, crash the system. (CVE-2014-3917,

Moderate)

 

This update also fixes the following bugs:

 

* A bug in the mtip32xx driver could prevent the Micron P420m PCIe SSD

devices with unaligned I/O access from completing the submitted I/O

requests. This resulted in a livelock situation and rendered the Micron

P420m PCIe SSD devices unusable. To fix this problem, mtip32xx now checks

whether an I/O access is unaligned and if so, it uses the correct

semaphore. (BZ#1125776)

 

* A series of patches has been backported to improve the functionality of

a touch pad on the latest Lenovo laptops in Red Hat Enterprise Linux 7.

(BZ#1122559)

 

* Due to a bug in the bnx2x driver, a network adapter could be unable to

recover from EEH error injection. The network adapter had to be taken

offline and rebooted in order to function properly again. With this update,

the bnx2x driver has been corrected and network adapters now recover from

EEH errors as expected. (BZ#1107722)

 

* Previously, if an hrtimer interrupt was delayed, all future pending

hrtimer events that were queued on the same processor were also delayed

until the initial hrtimer event was handled. This could cause all hrtimer

processing to stop for a significant period of time. To prevent this

problem, the kernel has been modified to handle all expired hrtimer events

when handling the initially delayed hrtimer event. (BZ#1113175)

 

* A previous change to the nouveau driver introduced a bit shift error,

which resulted in a wrong display resolution being set with some models

of NVIDIA controllers. With this update, the erroneous code has been

corrected, and the affected NVIDIA controllers can now set the correct

display resolution. (BZ#1114869)

 

* Due to a NULL pointer dereference bug in the be2net driver, the system

could experience a kernel oops and reboot when disabling a network adapter

after a permanent failure. This problem has been fixed by introducing a

flag to keep track of the setup state. The failing adapter can now be

disabled successfully without a kernel crash. (BZ#1122558)

 

* Previously, the Huge Translation Lookaside Buffer (HugeTLB) allowed

access to huge pages access by default. However, huge pages may be

unsupported in some environments, such as a KVM guest on a PowerPC

architecture, and an attempt to access a huge page in memory would result

in a kernel oops. This update ensures that HugeTLB denies access to huge

pages if the huge pages are not supported on the system. (BZ#1122115)

 

* If an NVMe device becomes ready but fails to create I/O queues, the nvme

driver creates a character device handle to manage such a device.

Previously, a character device could be created before a device reference

counter was initialized, which resulted in a kernel oops. This problem has

been fixed by calling the relevant initialization function earlier in the

code. (BZ#1119720)

 

* On some firmware versions of the BladeEngine 3 (BE3) controller,

interrupts remain disabled after a hardware reset. This was a problem for

all Emulex-based network adapters using such a BE3 controller because

these adapters would fail to recover from an EEH error if it occurred. To

resolve this problem, the be2net driver has been modified to enable the

interrupts in the eeh_resume handler explicitly. (BZ#1121712)

 

All kernel users are advised to upgrade to these updated packages, which

contain backported patches to correct these issues. The system must be

rebooted for this update to take effect.

 

4. Solution:

 

Before applying this update, make sure all previously released errata

relevant to your system have been applied.

 

This update is available via the Red Hat Network. Details on how to use the

Red Hat Network to apply this update are available at

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

 

To install kernel packages manually, use "rpm -ivh [package]". Do not use

"rpm -Uvh" as that will remove the running kernel binaries from your

system. You may use "rpm -e" to remove old kernels after determining that

the new kernel functions properly on your system.

 

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

 

1102571 - CVE-2014-3917 kernel: DoS with syscall auditing
