DESCRIPTION

* CVE-2016-2384: Privilege escalation in USB MIDI device driver.

The USB MIDI device driver does not correctly free memory when failing
to initialize an endpoint which can cause a use-after-free condition. A
local unprivileged user can use this flaw to trigger kernel code
execution.


* Data corruption when transmitting packets via Virtual Ethernet device.

A logic error can cause checksums to be ignored by the Virtual Ethernet
device driver which can cause corrupted data to be delivered to containers.

A logic error when parsing netfilter source chains can allow local users
to corrupt kernel memory.
