Security updates for Ubuntu 26.04
Fixes are backported by Canonical's Ubuntu Security Team and announced as Ubuntu Security Notices (USN), with ESM fixes for Ubuntu Pro subscribers after standard support ends. Read more about how security updates work on Ubuntu.
How OS Checker tracks it
OS Checker compares each machine's installed packages against Ubuntu's public archive and cross-references Ubuntu Security Notices to flag the updates that fix known CVEs, using Ubuntu's own priority. Updates delivered only through Ubuntu Pro's ESM repositories aren't part of the public archive, so they don't show up as available.
