Upgrade torvalds/linux to version 4.6.4 or higher.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). The key_reject_and_link function in security/keys/key.c in the Linux kernel through 4.6.3 does not ensure that a certain data structure is initialized, which allows local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command.
