Source: CISA Known Exploited Vulnerabilities catalog. The Ransomware flag reflects CISA's own knownRansomwareCampaignUse field, set when the CVE has been observed in ransomware campaigns per their threat intel. It's not a property of the vulnerability description itself.
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.
