DESCRIPTION

* CVE-2016-7910: Privilege escalation in /proc/partitions.

Incorrect cleanup when finishing reading /proc/partitions could result
in a use-after-free condition.  A local, unprivileged user could use
this flaw to crash the system, or potentially, escalate privileges.


* CVE-2016-7911: Privilege escalation in ioprio_get().

A race condition in retrieving the task IO context in the ioprio_get()
system call could allow a local, unprivileged user to trigger a
use-after-free and cause a denial-of-service, or potentially, escalate
privileges.
