Details
USN-3220-1 fixed a vulnerability in the Linux kernel. This update
provides the corresponding updates for the Linux kernel for Amazon
Web Services (AWS).

in the Linux kernel contained a double-free vulnerability. A local attacker
could use this to cause a denial of service (system crash) or possibly gain
administrative privileges.
