CVE-2024-33218Public exploit

Local privilege escalation via unrestricted IOCTL access

Published May 22, 2024 · Updated Feb 13, 2025

Privilege escalation in ASUS USB 3.0 Boost Storage Driver 5.30.20.0 allows local users to execute arbitrary code via crafted IOCTLs. AsUpIO64.sys exposes DeviceIoControl handlers that let unprivileged callers map physical memory and read or write I/O ports and model-specific registers. A local low-privileged account is required, after which the unrestricted kernel primitives support elevated code execution and information disclosure.
