CVE-2024-30064

Local privilege escalation through integer overflow

Published Jun 11, 2024 · Updated Aug 10, 2026

Windows kernel integer overflow in Windows Server 2022 and 23H2 allows local users to elevate privileges before builds 20348.2527 and 25398.950. Microsoft identifies the weakness as integer overflow but has not disclosed the affected kernel code path, arithmetic operation, or attacker-controlled value. Local low-privileged access is required, and successful exploitation crosses a security boundary to gain higher privileges.
