Microsoft’s June 2026 Patch Tuesday is the largest single release in the program’s history at 206 CVEs, including three publicly disclosed zero-days and CVSS 9.5 RCEs in Windows Kernel and HTTP.sys. Proof-of-concept code is publicly available for the BitLocker bypass and CTFMON privilege escalation, compressing the pre-weaponization window. No confirmed active exploitation is reported at time of analysis, but PoC availability elevates urgency for internet-facing Windows systems and endpoints.
