Microsoft June 2026 Patch Tuesday (record-breaker)
Microsoft’s June 2026 Patch Tuesday is the largest on record 200 CVEs (~33 critical), beating the prior high of 167.
Three publicly disclosed zero-days, none reported exploited in the wild yet:
•CVE-2026-45586 — Windows CTFMON EoP to SYSTEM
(“GreenPlasma”); flagged Exploitation More Likely
•CVE-2026-50507 — BitLocker security feature bypass
•CVE-2026-49160 — HTTP.sys (HTTP/2) DoS
Updates: Win11 KB5094126 / KB5093998, Win10 KB5094127 (ESU). The Win10 update also tracks the Secure Boot certificate rollover — certs start expiring this month.
Test, then deploy. Prioritize the zero-days and critical RCEs.
