CVE-2025-62219

Local privilege escalation via double-free race

Published Nov 11, 2025 · Updated Nov 11, 2025

Double free in Microsoft Wireless Provisioning System on affected Windows releases allows local users to elevate privileges. Microsoft identifies improper synchronization and a double free but has not disclosed the affected function or operation that releases the allocation twice. A low-privileged local user must win a race condition; successful exploitation grants higher privileges with confidentiality, integrity, and availability impact.
