Use after free in Windows DHCP Server allows an unauthorized attacker to execute code over a network.
AnalysisAI
Remote code execution in Microsoft Windows DHCP Server (the DHCP role across Windows Server 2012 through 2025 and Windows 10 1607/1809) stems from a use-after-free condition that an unauthenticated attacker can trigger over the network to run arbitrary code in the DHCP service context. The flaw carries a CVSS 9.8 with no privileges or user interaction required, and Microsoft has shipped a fix via MSRC; no public exploit has been identified at time of analysis. …
