Heap-based buffer overflow in Windows DHCP Server allows an unauthorized attacker to execute code over a network.
AnalysisAI
Remote code execution in the Microsoft Windows DHCP Server role allows an unauthenticated network attacker to run arbitrary code by triggering a heap-based buffer overflow (CWE-122) in the service's packet handling. The flaw carries a CVSS 9.8 with a fully remote, no-interaction, no-privilege vector and affects Windows Server 2012 through 2025 (plus the Windows 10 1607/1809 code base). At time of analysis there is no public exploit identified and the issue is not listed in CISA KEV, but the unauthenticated network-facing nature of the DHCP service makes it a high-priority patch.
