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
"This issue is limited to motherboards and does not affect laptops, desktop computers, or other endpoints." An insufficient validation vulnerability in ASUS DriverHub may allow untrusted sources to affect system behavior via crafted HTTP requests. Refer to the 'Security Update for ASUS DriverHub' 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

An insufficient validation vulnerability in ASUS DriverHub allows untrusted sources to manipulate system behavior through crafted HTTP requests. This issue specifically affects motherboards and stems from improper input validation in the DriverHub software's HTTP communication handling, potentially allowing man-in-the-middle or HTTP downgrade attacks to influence driver update processes.

MitigationApply the security update for ASUS DriverHub as specified in the ASUS Security Advisory. Since this affects only motherboards with DriverHub installed, identify and update all affected motherboard systems. Consider network-level controls to validate HTTP traffic sources until patching is complete.

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. Verify ASUS DriverHub installation
    Check for ASUS DriverHub in the system: On Windows, open Control Panel > Programs and Features, or run 'Get-WmiObject -Class Win32_Product | Where-Object {$_.Name -like "*DriverHub*"}' in PowerShell. Also check for the DriverHub service using 'Get-Service | Where-Object {$_.Name -like "*DriverHub*"}' or review installed programs in the registry at HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
    Affected if ASUS DriverHub is listed as an installed program or service on the system
  2. Identify DriverHub version
    If DriverHub is installed, locate its version: Right-click the DriverHub application shortcut or executable, select Properties, and check the Details tab for Product Version. Alternatively, check the registry key HKLM\SOFTWARE\ASUS\DriverHub\Version if it exists, or examine the version info of the main DriverHub executable in its installation directory (commonly under C:\Program Files\ASUS\DriverHub or C:\Program Files (x86)\ASUS\DriverHub)
    Affected if The installed version matches or falls within the affected version range for CVE-2025-3463 (compare your installed version to the official ASUS advisory for the vulnerable versions)
  3. Confirm HTTP-based update mechanism is active
    Since the vulnerability involves HTTP communication handling in driver updates, check if automatic driver updates are enabled: Open DriverHub, go to Settings or Options, and verify whether automatic driver download/update checks are turned on. Also check if the system is configured to receive driver updates via HTTP rather than HTTPS by examining DriverHub configuration files or network traffic settings related to ASUS update servers
    Affected if Automatic driver updates or HTTP-based update checking is enabled in DriverHub settings, making the system vulnerable to HTTP downgrade or MITM attacks during driver update processes

A system is affected if it has ASUS DriverHub installed with a vulnerable version AND has HTTP-based driver update functionality enabled, as the vulnerability requires both the software presence and the HTTP communication channel to be active.
