SYSTEM privilege escalation via untrusted pointer dereference
Published Dec 10, 2024 · Updated Jun 9, 2026
Untrusted pointer dereference in the Microsoft Windows Common Log File System Driver allows local users to gain SYSTEM privileges. Microsoft identifies the CLFS driver and CWE-822 but has not published the affected function or the precise operation that dereferences the attacker-controlled pointer. Exploitation requires prior low-privilege local access and is bounded to privilege escalation on the affected host.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
