Microsoft shipped 970 fixes this month, 113 of them rated Critical. A further 216 entries in the same document are third-party CVEs Microsoft republishes or Edge/Chromium updates, carrying 6 Critical — counted separately here, because that total tracks Microsoft's role as a CNA rather than the size of Patch Tuesday. 3 are already under active attack and should be patched today; 0 publicly disclosed zero-days should be closed this week. Everything else fits the normal monthly cycle.
As of 2026-09-09 15:42 UTC, this cycle’s MSRC document lists 1,186 CVEs — 970 Microsoft-authored, plus 24 Edge/Chromium and 192 Linux/other entries that are republished third-party fixes patching through their own vendors. That figure is a reading at a timestamp, not a fixed total for the month: Microsoft revises this document in place, and it is currently at revision 222 (last revised 2026-09-09 15:09 UTC). The two Critical lines above are kept separate for the same reason — the third-party total moves with Microsoft’s CNA scope, not with the size of Patch Tuesday.
Confirmed in CISA KEV and flagged as exploited by Microsoft. Treat as active incidents, not routine patching.

Authoritative counts and exploitation flags come from Microsoft's MSRC Security Update Guide and CISA's Known Exploited Vulnerabilities catalog. Independent reporting and analyst commentary corroborate and add context but do not set priority.
Ranking is a composite score that weights active exploitation and public disclosure above raw CVSS, adjusted for network-reachable / no-authentication attack profiles and field-analyst judgment — which is why a low-CVSS vulnerability under active attack can outrank an unexploited 9.8.
