Microsoft Issues Record 570 Security Patches, Including Three Zero-Days
Key points
- 570 security flaws addressed in July 2026 Patch Tuesday.
- Three zero-day vulnerabilities patched, two actively exploited.
- AI-driven discovery contributed to the increase in patches.
- Record-breaking patch count for second month consecutively.
Overview
Microsoft's July 2026 Patch Tuesday marked a record with updates addressing 570 security vulnerabilities across its software lineup, including Windows and Office. Three zero-day flaws were among the patched vulnerabilities, two of which were actively exploited before discovery.
Details of Zero-Day Flaws
The zero-day vulnerabilities included one in Active Directory Federation Services (CVE-2026-56155) and another in Microsoft SharePoint (CVE-2026-56164). Both allowed attackers to escalate their privileges. Another exploit in Windows BitLocker, CVE-2026-50661, could lead to data access if a device was physically compromised.
AI-Driven Discovery
Microsoft credited the surge in identified vulnerabilities partly to the use of artificial intelligence. AI tools have enabled the discovery of numerous security issues, reflecting an industry trend towards increased use of technology to pre-emptively identify vulnerabilities.
Significance and Actions
This record-breaking update follows similarly large releases in previous months, showing a consistent uptick in vulnerability discovery and remediation. Users are urged to apply the patches immediately to secure systems, as unpatched vulnerabilities pose significant risks.
