CVE-2022-44898Public exploit

Local privilege escalation via unchecked IOCTL buffer length

Published Dec 14, 2022 · Updated Apr 22, 2025

Stack-based buffer overflow in ASUS Aura Sync 1.07.79 and earlier allows local users to gain kernel privileges via crafted IOCTL requests. The MsIo64.sys IOCTL dispatch routine copies a caller-controlled input buffer into a two-element stack array with memmove without validating its length. A low-privileged Windows user who can open the driver device can overwrite the dispatch return address for kernel code execution or crash the host.
