How to check kernel "livepatch" version?

[Daniel Howard]

Hello,

Regarding LSN-0037-1, posted to ubuntu-security last week: how does one
verify that they are running a properly patched kernel? All of my apt-based
tools refer to the kernel version as, for example, 4.4.0.121.127, but the
security announcement refers to a "livepatch version" ... which appears to
be a commercial subscription service.

If I am not a livepatch subscriber, what kernel version should I be running
to be safe against the vulnerabilities disclosed in LSN-0037-1?

Thanks,
-danny
