Correlation is at the platform level, not per-OS-version. Not exhaustive: KEV only lists actively-exploited CVEs and many relevant unexploited vulnerabilities are not here. Verify against vendor security advisories (PSIRT, JSA, PAN-SA) and NVD before acting. See compensating controls if refresh isn't immediate.
