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
Out-of-bounds Read in ASUS System Control Interface v3, ASUS System Control Interface, and ASUS Business Manager allows a local administrator to read memory regions beyond the intended firmware boundary by supplying a crafted IOCTL request that bypasses the validation. Refer to the ' Security Update for ASUS System Control Interface  ' 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 confidence

Out-of-bounds read vulnerability in ASUS System Control Interface drivers (v3, standard, and Business Manager) allows a local administrator to read memory beyond the intended firmware boundary via a crafted IOCTL request that bypasses input validation. This is a kernel-mode driver flaw resulting in information disclosure.

MitigationApply the vendor patch from ASUS Security Advisory when available; until then, restrict administrative access and monitor for suspicious IOCTL calls. The fix requires updating the driver with proper bounds checking in the IOCTL handler.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed ASUS System Control Interface drivers
    Open Device Manager, expand 'System devices', and look for 'ASUS System Control Interface' or related entries. Also check Programs and Features for ASUS-related software packages.
    Affected if Any ASUS System Control Interface driver (v3, standard, or Business Manager) is installed and the version is within the vulnerable range disclosed in ASUS Security Advisory ASA-2026-001 or later.
  2. Locate and identify the driver file
    Search for ASUS kernel drivers in %SystemRoot%\System32\drivers\ (e.g., AsSysCtrlDrv.sys, AsusSysCtrl.sys, or similar naming patterns). Use 'driverquery /v' or 'Get-ItemProperty' on suspected driver files to retrieve version info.
    Affected if A driver file with 'SysCtrl', 'SystemControl', or 'ASUS' in the name exists and its version matches the vulnerable versions from the ASUS advisory.
  3. Verify the driver is loaded in kernel memory
    Run 'sc query asus' or 'driverquery /v | findstr -i asus' to check if the ASUS driver service is running. Also check with 'lsdriver' or 'fltmc' if available.
    Affected if The ASUS System Control Interface driver service is in a 'Running' state, meaning the IOCTL handler is active and processing requests.
  4. Check for exposed IOCTL device interface
    Use 'winobj' or 'device tree' tools to examine \Device\ and \GLOBAL??\ for ASUS device objects (commonly named '\\Device\\ASUS_System_Control_Interface' or similar). Run 'ls -la /dev/asi*' on WSL if applicable, or monitor with Process Monitor for DeviceIoActivity.
    Affected if An ASUS device interface is present and accessible, indicating the IOCTL entry point exists for the vulnerable handler.
  5. Review IOCTL code paths for vulnerability indicators
    If you have access to the driver binary, analyze IOCTL codes 0x9c40xxxx ranges (common for ASUS sysctrl). Monitor with tools like DriverMon or IOCTLizer for any out-of-bounds memory access patterns using 'WinDbg' or 'OSR Debugger' attached to the driver.
    Affected if The driver processes IOCTL requests without proper bounds validation, allowing memory reads beyond firmware boundaries. This is confirmed by the vendor advisory.

A system is affected if ASUS System Control Interface (v3, standard, or Business Manager) driver is installed and running, with a version that falls within the vulnerable range specified in the official ASUS security advisory.
