The patch addresses a total of nine security vulnerabilities
[...] All these flaws could [allow] local attackers to either crash the system or execute arbitrary code, bypass intended access restrictions to the connection tracking helpers list, as well as to inappropriately modify the system-wide operating system fingerprint list. Canonical urges all Ubuntu 16.04 LTS and Ubuntu 14.04 LTS users using the Canonical Livepatch to update their system immediately. A restart is not required when updating the kernel [using the] live patch.

--I'm willing to admit I just *might* be wrong... Are you?
