CVE-2024-38248

Local privilege escalation via use-after-free

Published Sep 10, 2024 · Updated Aug 10, 2026

Use-after-free in Windows Storage allows local users on affected Windows releases to elevate privileges through local access. Microsoft identifies the affected component only as Windows Storage and has not disclosed which object is freed prematurely or later reused. Exploitation requires low-privileged local access and high-complexity conditions; successful exploitation grants elevated control over data and system operation.
