Microsoft’s February 2026 Patch Tuesday fixes 58 vulnerabilities — including six actively exploited zero-days — affecting Windows, Office, and Remote Desktop components; impacts range from SmartScreen and MSHTML security bypasses and remote code execution to SYSTEM-level privilege escalations and a network service denial-of-service. CISA added all six zero-days to its Known Exploited Vulnerabilities catalog and set a March 3, 2026 patch deadline for federal agencies, making rapid mitigation urgent.
