I'm not seeing 11.6 on on my MacBook Air M1. I have 11.5.2 and it says I'm up to date.

Security Update 2021-005 Mojave ('https://support.apple.com/kb/HT212603') [21 Jul 2021]
Security Update 2021-005 Catalina ('https://support.apple.com/kb/HT212805') [13 Sep 2021]

Mojave is in its end of life... Apple will only support Monterey plus Big Sur and Catalina moving forward...

I'm not able to find a source but this is based on previous macOS versions...
Mojave is the last OS which supports 32 bit applications. Hence maybe Apple would support a little longer than previous OS. ?
(Or, Mojave simply don't have this issue??)

All Macs that support Mojave support Catalina, so Apple probably decided not to bother. People who are afraid to run their Macs without security updates probably run Catalina or unsupported Monterey/Big Sur already.
Repeat after me: 32 bit application support. ;)
