Microsoft Security Update Releases (MSRC)

msrc/security-updates

Every Microsoft Security Response Center security update release, newest first: the release id (year and month, for example 2026-Sep), its title, the first publication date and the latest revision date (ISO 8601 UTC) and the URL of the full CVRF document. Ids before 2016 are Azure Linux notes titled Mariner Release Notes. Use the release-lookup tool to resolve a CVE id to its release.
