What it checks
Running kernel differs from the newest installed (reboot pending).
Why it matters
The patched kernel is not yet active — kernel vulns remain exposed.
How to fix
Reboot into the newest kernel during a maintenance window.
InfraGuard runs all 36 checks across your servers at once and grades each host A–F.
Track these versions on your own servers
