CVE-2025-6398

Privileged local system crash via null pointer dereference

Published Aug 1, 2025 · Updated Aug 1, 2025

Null pointer dereference in ASUS AI Suite 3 before 3.03.42 allows local users to crash Windows through crafted IOMap64.sys input. IOMap64.sys accepts the crafted input and dereferences a null pointer instead of rejecting it, causing a kernel-level fault. Exploitation requires high local privileges and no user interaction; the bounded consequence is a system crash and BSOD, not data access or code execution.
