Details

USN-3292-1 fixed a vulnerability in the Linux kernel for Ubuntu 16.10.
This update provides the corresponding updates for the Linux Hardware
Enablement (HWE) kernel from Ubuntu 16.10 for Ubuntu 16.04 LTS.

Jason Donenfeld discovered a heap overflow in the MACsec module in the
Linux kernel. An attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code.
