If I'm reading it right, all those patches are also available for Sierra 10.12.6 and El Capitan 10.11.6 (and will presumably be delivered by an update there), except for the ones that say don't apply to Sierra 10.12.6 (the vulnerability doesn't exist there).

Eg:

> macOS High Sierra 10.13.1, macOS Sierra 10.12.6, OS X El Capitan 10.11.6

And:

> Available for: macOS High Sierra 10.13 and macOS High Sierra 10.13.1

> Not impacted: macOS Sierra 10.12.6 and earlier
