CVE-2024-20698

Local privilege escalation via kernel integer overflow

Published Jan 9, 2024 · Updated Jun 3, 2025

Integer overflow in the Microsoft Windows Kernel allows local users with low privileges to elevate privileges on affected Windows releases. Microsoft identifies CWE-190 but has not disclosed the affected kernel routine, attacker-controlled value, or arithmetic operation that wraps. Exploitation requires local low-privilege access and no user interaction; the public record does not identify the resulting account or token level.
