Perhaps Greg-KH was implicitly including Ubuntu under Debian?

Yea I don't use Linux too often but how different is an Ubuntu kernel compared to a Debian kernel? I know Ubuntu is downstream from Debian or at least they were. So how much extra work/code does Canonical add to its kernels.

  Canonical had Spectre and Meltdown mitigations out for their kernels before Debian did, and he also specifically mentions Canonical as getting alerted, so apparently enough.

    I think there should be a distinction between Canonical and debian, but Ubuntu is certainly based on Debian, and the latter should be used when talking big scale like he did. Many cloud services and providers run on Ubuntu, and as long as Ubuntu uses apt and .deb, it's Debian (along with Linux Mint, elementaryOS, etc)

      > and as long as Ubuntu uses apt and .deb, it's Debian No, there is more to a distro than them sharing a common package manager/format. The kernel, which is heavily patched by canonical, differs from what Debian ships. Canonical also has a bad habit of carrying a lot of non-upstream patches for other core system components. Ubuntu may have been derived from Debian at one point, but they are fairly different at this point. So much so that you cannot take a system running Debian and 'upgrade' (or downgrade, depending on your point of view) it to one running Ubuntu.

        Actually, you can smash Debian & ubuntu together, you just get a terrible monster called frankendebian. As a youngster I tried this, it didn't pan out.

        A distro, for the most part is 1) package manager + repos, and 2) system organization (where things get installed, where configs are, how services are managed etc). In that respect, Ubuntu is still Debian - most packages are vanilla Debian packages, and they both use systemd.

That doesn't say much, as sometimes ubuntu and debian upgrades are far from smooth. As a long Debian & Ubuntu user, I believe you're exagerating the work invested by Ubuntu to custonize Debian. Betond the default desktop environment and attitude regarding proprietary drivers, the work done by Ubuntu is rather negligible.

    Canonical was alerted, but they still had a delay of several weeks before they had an update.

    That's not true. - https://www.debian.org/security/2018/dsa-4078 https://www.debian.org/security/2018/dsa-4078 (January 4th) - https://usn.ubuntu.com/3522-1/ https://usn.ubuntu.com/3522-1/ (January 9th) Canonical got caught in the shortened embargo and didn't modify their schedule while everyone else did.

As mentioned in the article, Canonical were brought in much earlier by Intel. They appear to have been among the "chosen few": RedHat, SuSE and Canonical.
