CVE-2022-4990
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 bypass security validation and access restricted memory blocks 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 · high confidenceThis is a local privilege escalation vulnerability in the ASUS AI Suite 3 driver. The driver fails to properly validate specified quantity in input fields, allowing a local authenticated user to send crafted IOCTL (I/O Control) requests that bypass security validation and access restricted memory blocks. This enables an attacker to escalate privileges on the affected system.

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 installationLook for the application in Add/Remove Programs (Windows) or check for the installation directory typically at C:\Program Files\ASUS\AI Suite 3 or C:\Program Files (x86)\ASUS\AI Suite 3Affected if ASUS AI Suite 3 is installed on the system
-
Identify the ASUS driver componentSearch for ASUS driver files (.sys) in the installation directory and subfolders, typically under C:\Windows\System32\drivers or the AI Suite 3 program directoryAffected if ASUS kernel driver files (typically .sys extension) are present on the system
-
Verify if the driver is loadedOpen an elevated command prompt and run 'sc query' or check Device Manager for ASUS-related drivers under the 'System devices' or 'Non-plug and Play Drivers' sectionAffected if An ASUS driver is currently loaded or active in the system
-
Check driver version informationRight-click on the identified .sys driver file, select Properties, then go to the Details tab to view File Version and Product Version informationAffected if The driver file version cannot be confirmed as patched or falls within an unverified version range
-
Review driver file permissionsRight-click the driver file, select Properties > Security tab to see which user groups have read, write, or execute permissions on the driverAffected if Unprivileged users have write or modify access to the driver file
The system is affected if ASUS AI Suite 3 is installed with its driver present and loaded, and the installed version is not confirmed as patched by the vendor.

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 this driver is marked as unsupported/end-of-life, the primary remediation is to remove or disable the vulnerable ASUS AI Suite 3 driver and replace with updated drivers if available, or discontinue use of the software entirely.
