CVE-2026-61361

Local code execution via DHCP Client use-after-free

Published Aug 11, 2026 · Updated Aug 25, 2026

Use-after-free in Windows DHCP Client in Microsoft Windows 11 24H2-26H1 and Windows Server 2025 allows local authenticated users to execute code. Microsoft has not disclosed the affected function or trigger; the published record identifies a use-after-free in Windows DHCP Client, meaning the component dereferences stale memory after the backing allocation has been released. Reachability requires local authenticated access with low privileges, and reviewed public records as of August 19, 2026 do not describe a remote trigger, user interaction requirement, or in-the-wild exploitation.
