Microsoft discloses ‘the mother of all’ vulnerability loads, tripling June’s previous record

Microsoft released a record-setting Patch Tuesday addressing 622 vulnerabilities across its products — including 416 in Windows, 82 in Office and 46 in Edge — and disclosed two actively exploited zero-days (CVE-2026-56155 and CVE-2026-56164); the surge is attributed to AI-assisted scanning (MDASH) that has rapidly increased detection of defects, though many findings may not pose immediate operational risk.
