Ubuntu Security Notice USN-3084-4
September 19, 2016

linux-snapdragon vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-snapdragon: Linux kernel for Snapdragon Processors

Details:

Pengfei Wang discovered a race condition in the audit subsystem in the
Linux kernel. A local attacker could use this to corrupt audit logs or
disrupt system-call auditing. (CVE-2016-6136)

It was discovered that the powerpc and powerpc64 hypervisor-mode KVM
implementation in the Linux kernel for did not properly maintain state
about transactional memory. An unprivileged attacker in a guest could cause
a denial of service (CPU lockup) in the host OS. (CVE-2016-5412)

Pengfei Wang discovered a race condition in the Chrome OS embedded
controller device driver in the Linux kernel. A local attacker could use
this to cause a denial of service (system crash). (CVE-2016-6156)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 LTS:
  linux-image-4.4.0-1026-snapdragon  4.4.0-1026.29

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
