Microsoft Patches Record 1,413 Vulnerabilities, Including Actively Exploited Windows Zero-Day

Microsoft's October 2026 Patch Tuesday addressed a record 1,413 vulnerabilities across its products, including Windows, Office, and developer tools. This extensive update includes fixes for an actively exploited Windows zero-day (CVE-2026-96951) and two publicly disclosed zero-days. The significant increase in reported flaws, partly attributed to AI-assisted vulnerability discovery, highlights increasing pressure on corporate security teams to manage and deploy these numerous fixes.
