Microsoft Patch Tuesday August 2026, (Tue, Aug 11th)

Microsoft released patches for four hundred eighteen vulnerabilities this month, including sixty-two rated critical. Per SANS ISC Diary, one is already being exploited in the wild, and two were publicly disclosed before patches became available. Two critical remote code execution bugs pose the greatest immediate threat: Microsoft QUIC—a modern internet protocol—and Windows DNS Server, both carrying maximum severity scores of nine point eight and exploitable by unauthenticated attackers over the network. A locally exploited elevation of privilege flaw in the Windows Ancillary Function Driver for WinSock could allow low-privileged users to gain system-level access. Administrators should prioritize patching DNS and QUIC services exposed to untrusted networks, then deploy the remainder across Windows systems to close publicly disclosed gaps and contain the active exploitation threat.
