What the Fix column means

A KB means we hold Microsoft's own remediation data for that CVE: the update that fixes it and, where Microsoft publishes one, the build revision that carries the fix. That is the difference between knowing a CVE exists and knowing whether the machine in front of you is still exposed to it.

If you want that answered for a specific machine rather than a specific CVE, paste your build into the patch checker. It walks the supersedence chain, so it can tell you that the update you actually installed covers a fix that shipped in an earlier one.

Where the data comes from

CVE records, CVSS scores and descriptions come from NVD. The exploited flag comes from CISA's KEV catalog. Windows fix data comes from Microsoft's own security update feed. We are not endorsed by or certified by any of them.
