Microsoft's September 2026 Patch Tuesday fixes record ~972 flaws, 2026 total more than doubles 2025
↗
Microsoft's September 2026 Patch Tuesday addresses a record approximately 972 vulnerabilities, bringing the year's total to 2,760, more than double the 2025 figure.
The sheer volume of patches means organizations must prioritize which vulnerabilities to address first, as patching everything may be infeasible. The doubling of total fixes from 2025 suggests an accelerating rate of discovered vulnerabilities, likely increasing the operational burden on security teams. Engineers should expect more frequent emergency patching cycles and plan for automated patch management.
