CVE-2022-4989
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · unedited** UNSUPPORTED WHEN ASSIGNED ** Improper Validation of Specified Quantity in Input in the ASUS AI Suite 3 driver allows a local user to access unintended memory regions via crafted IOCTL requests, leading to privilege escalation. Refer to the 'End-of-Life Notice and Driver Update for Legacy ASUS Drivers ' section on the ASUS Security Advisory for more information.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA local privilege escalation vulnerability in the ASUS AI Suite 3 Windows kernel-mode driver stems from improper validation of input quantities in IOCTL requests. A local attacker can craft malicious IOCTL requests to access unintended memory regions, corrupting kernel memory and escalating privileges to SYSTEM level.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check for ASUS AI Suite 3 installationOpen Programs and Features (appwiz.cpl) or check C:\Program Files\ASUS\AI Suite 3 for the presence of the application folder and executable filesAffected if ASUS AI Suite 3 is installed on the system
-
Identify the vulnerable driver fileSearch for ASUS driver files in the system, typically found in C:\Windows\System32\drivers\ with names like AsUsbCatIO.sys, AsIO.sys, or similar ASUS kernel drivers. Use 'dir /s /b C:\*.sys | findstr -i asus' in an elevated command promptAffected if Any ASUS kernel driver files associated with AI Suite 3 are present on the system
-
Check if the driver is loaded as a serviceOpen Services (services.msc) and look for ASUS-related services, or run 'sc queryex type= service' and filter for ASUS entries. Also check with 'driverquery /v | findstr -i asus'Affected if An ASUS driver service is registered and running on the system
-
Verify the driver is active in memoryRun 'sc queryex type= driver' or check Device Manager for ASUS filter/driver devices under System Devices. Use Process Explorer or Process Hacker to check for related kernel drivers loadedAffected if The ASUS AI Suite 3 driver is loaded into kernel memory
-
Check for ASUS AI Suite 3 running processesOpen Task Manager or run 'tasklist /v | findstr -i asus' to see if AI Suite 3 application components are actively runningAffected if AI Suite 3 processes are executing with the driver present
If the ASUS AI Suite 3 application and its associated kernel driver are installed and present on the system, the environment is vulnerable to this privilege escalation flaw.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataSince ASUS AI Suite 3 driver is end-of-life and unsupported, organizations should remove or disable the software entirely. If the software is still required for business functions, contact ASUS for alternative solutions or implement compensating controls such as restricting local user access and monitoring for exploitation attempts.
