GoKawiilMicrosoft's September 2026 Patch Tuesday sets record with 966 fixes, two exploited zero-days
Microsoft's latest Patch Tuesday release addresses 966 vulnerabilities, its largest batch ever, including 105 rated Critical and two zero-days already being exploited in the wild. The count excludes 204 additional flaws Microsoft patched earlier in the month across products like Azure AI Language, Copilot Studio, and Entra ID.
GoKawiil's interpretation of the reporting above, not reported fact.
The jump from 570 fixes in July and 400 in August to nearly 1,000 this month reflects Microsoft's new AI-powered vulnerability discovery tool surfacing far more bugs than manual review ever did. For IT teams, this means patch management workloads are growing sharply, while the presence of actively exploited zero-days makes prompt deployment urgent despite the sheer volume.
- 966 vulnerabilities patched, the largest Patch Tuesday release on record
- Two zero-day flaws were already being actively exploited before the fix
- AI-assisted vulnerability discovery is driving a steep rise in monthly patch counts
