Details:

USN-4163-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04

LTS. This update provides the corresponding updates for the Linux

Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu

Update Instructions

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

Ubuntu 14.04 ESM:
  linux-image-4.4.0-1056-aws      4.4.0-1056.60
  linux-image-4.4.0-166-generic   4.4.0-166.195~14.04.1
  linux-image-4.4.0-166-generic-lpae  4.4.0-166.195~14.04.1
  linux-image-4.4.0-166-lowlatency  4.4.0-166.195~14.04.1
  linux-image-4.4.0-166-powerpc-e500mc  4.4.0-166.195~14.04.1
  linux-image-4.4.0-166-powerpc-smp  4.4.0-166.195~14.04.1
  linux-image-4.4.0-166-powerpc64-emb  4.4.0-166.195~14.04.1
  linux-image-4.4.0-166-powerpc64-smp  4.4.0-166.195~14.04.1
  linux-image-aws                 4.4.0.1056.57
  linux-image-generic-lpae-lts-xenial  4.4.0.166.145
  linux-image-generic-lts-xenial  4.4.0.166.145
  linux-image-lowlatency-lts-xenial  4.4.0.166.145
  linux-image-powerpc-e500mc-lts-xenial  4.4.0.166.145
  linux-image-powerpc-smp-lts-xenial  4.4.0.166.145
  linux-image-powerpc64-emb-lts-xenial  4.4.0.166.145
  linux-image-powerpc64-smp-lts-xenial  4.4.0.166.145
  linux-image-virtual-lts-xenial  4.4.0.166.145

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.
