Ubuntu Security Notice USN-3035-1
July 14, 2016

linux vulnerability

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

- Ubuntu 15.10


The system could be made to crash under certain conditions.

Software Description:
- linux: Linux kernel


Jan Stancek discovered that the Linux kernel's memory manager did not
properly handle moving pages mapped by the asynchronous I/O (AIO) ring
buffer to the other nodes. A local attacker could use this to cause a
denial of service (system crash).

Update instructions:

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

Ubuntu 15.10:
  linux-image-4.2.0-42-generic    4.2.0-42.49
  linux-image-4.2.0-42-generic-lpae  4.2.0-42.49
  linux-image-4.2.0-42-lowlatency  4.2.0-42.49
  linux-image-4.2.0-42-powerpc-e500mc  4.2.0-42.49
  linux-image-4.2.0-42-powerpc-smp  4.2.0-42.49
  linux-image-4.2.0-42-powerpc64-emb  4.2.0-42.49
  linux-image-4.2.0-42-powerpc64-smp  4.2.0-42.49

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.
