Microsoft patches a record 570 flaws in AI-augmented Patch Tuesday
Microsoft released a record Patch Tuesday fixing at least 570 vulnerabilities across Windows and related software, driven by AI-driven vulnerability discovery; about 60 are critical and three zero-days are already being exploited. Highlights include CVE-2026-56155 (Active Directory Federation Services), CVE-2026-56164 (SharePoint), and CVE-2026-50661 (BitLocker bypass), plus a Copilot remote code execution flaw (CVE-2026-48561). Industry experts warn exploitability ratings may lag AI-enabled discovery as patch cadences rise across vendors. Users are advised to back up systems and consider delaying updates if stability is a concern.
