Microsoft's Latest Patch Tuesday Breaks Records: 974 Vulnerabilities Fixed

Dark Reading · 9 Sept 2026

Key Takeaway Apply Microsoft's latest security updates promptly, especially on systems affected by the actively exploited vulnerabilities, to reduce your risk of compromise.

Microsoft has released its largest Patch Tuesday update on record, fixing 974 vulnerabilities across its products. Two of these flaws are already being actively exploited by attackers, while Microsoft has flagged another 58 as more likely to be targeted in the near future.

Patch Tuesday updates are Microsoft's monthly rollout of security fixes, and the sheer volume this month highlights how quickly new weaknesses are being discovered across widely used software. For small businesses, delays in applying these updates can leave systems exposed to known attack methods that cybercriminals are actively using.

Businesses running Microsoft products should prioritise applying updates as soon as possible, particularly for the vulnerabilities already under active exploitation. IT teams or managed service providers should review Microsoft's guidance to identify which systems are most at risk and patch accordingly.
