Debian 11 (Bullseye)
Debian 11 is in maintenance: its free LTS support has ended, and security fixes now come only through Freexian's commercial Extended LTS.

Debian 11 isn't tracked by OS Checker. The remaining security fixes for it come through a separate, paid program rather than the regular repositories. Upgrading to Debian 13, the current release, gets you full support again - and lets OS Checker keep track of its updates.
Security updates for Debian 11
Fixes are backported by the Debian Security Team, and later the Debian LTS team, announced as DSA or DLA advisories and recorded in the Debian Security Tracker. Read more about how security updates work on Debian.
