CVE-2026-58544: Microsoft Windows Management Services use after free privilege escalation

CVE-2026-58544 · Severity: high · CVSS 7 · Published 2026-07-14

Technologies: Microsoft Windows 11 Version 25H2, Microsoft Windows 11 Version 24H2, Microsoft Windows 11 Version 26H1, Microsoft Windows Server 2025, Microsoft Windows 11. Vendors: Microsoft.

Executive brief

A security vulnerability exists in Windows Management Services, a component used for managing and monitoring Windows systems. An attacker who already has basic access to a computer could exploit this flaw to gain full administrative control. This could allow them to access sensitive data, install malicious software, or disrupt business operations.

Technical details

A use-after-free vulnerability (CWE-416) exists in Windows Management Services. The flaw is triggered when the service incorrectly handles objects in memory, allowing an attacker to reuse a memory pointer after it has been freed. To exploit this, an attacker must have local access to the system with low-level user privileges. Successful exploitation allows the attacker to execute code with elevated system privileges. Microsoft has released security updates to address this issue across affected versions of Windows 11 and Windows Server 2025.
