October 2026 Patch Tuesday: 3 Zero-Days, 75 Critical CVEs
- Engineer — Plan: Three zero-days in a Patch Tuesday cycle indicate pre-patch exploitation; pull the full Microsoft advisory list, identify which zero-days and critical CVEs affect your stack, and advance patch timelines for those specifically — no enrichment signals yet confirm KEV listing or PoC availability for prioritization beyond that.
- SOC/IR — Plan: Zero-days exploited before patch release means adversaries had a head start; once Microsoft publishes full technical detail, build or tune detections for the affected components and run a targeted hunt for exploitation activity since the start of October.
- Leader — Learn: Routine Patch Tuesday scale, even at 1,413 CVEs with three zero-days, does not rise to board-level action without a named systemic event — monitor whether any zero-day affects widely-used enterprise software that could trigger a vendor-exposure inquiry.
