CVE-2025-47975

Local privilege escalation via SSDP double free

Published Jul 8, 2025 · Updated Feb 13, 2026

A double-free flaw in the Windows SSDP Service allows local users with authorization to elevate privileges on affected Windows systems. Microsoft identifies the memory-management error as a double free but has not disclosed the affected function, object lifetime, or attacker-controlled input that triggers the second release. Successful exploitation requires local low-privileged access and grants elevated control, while the published high attack complexity indicates additional conditions must align.
