CVE-2024-43553

Kernel privilege escalation via untrusted pointer dereference

Published Oct 8, 2024 · Updated Aug 19, 2026

Elevation of privilege in the Microsoft Windows NT OS Kernel allows local users to gain kernel-level privileges via local execution. Microsoft identifies an untrusted pointer dereference but has not published the affected kernel routine or the input path supplying the pointer. Exploitation requires high-complexity local conditions; success grants control at kernel privilege.
