• Confirming a security patch actually landed: matching installed versions against vendor advisories across OS families

  An update job reporting success is not proof a specific vulnerability is fixed; matching the installed package or build version against the vendor's own advisory — Ubuntu USN, a RHEL-family advisory (RHSA on RHEL) via dnf updateinfo --security, Debian DSA via debsecan, Windows Get-HotFix, or a macOS build number against Apple's own security-release page — is what closes the loop, and a pending restart can leave the old, vulnerable binary still running even after that check passes.
