DESCRIPTION

* CVE-2016-3070: Denial of service when migrating dirty pages.

A NULL pointer dereference could happen when migrating dirty pages from an
AIO ring buffer to another node.  A local, unprivileged user could use this
flaw to cause a denial-of-service.


* CVE-2015-8956: NULL pointer dereference in the Bluetooth stack.

A missing NULL pointer check when binding to a bluetooth socket could cause
a NULL pointer dereference.  A local user with privileges to bind a
bluetooth socket could use this flaw to cause a denial-of-service.


* CVE-2016-4578, CVE-2016-4569: Information leak in sound timers.

Missing initialization of stack data structures could result in leaking
the contents of kernel stack memory to user-space.  A local user with
access to the sound device could use this flaw to infer the layout of
kernel memory.


* NULL pointer dereference in Infiniband CSI RDMA Protocol Target.

Missing SRP targets could result in a NULL pointer dereference and
subsequent kernel crash under specific conditions.


* CVE-2016-6480: Denial-of-service in Adaptec AACRAID driver.

A race condition in fetching parameters from userspace could result in
accessing beyond the bounds of a buffer.  A local user with privileges
to access the device could use this flaw to crash the system.
