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
In preloader (usb), there is a possible permission bypass due to a missing proper image authentication. This could lead to local escalation of privilege, for an attacker who has physical access to the device, with no additional execution privileges needed. User interaction is needed for exploitation. Patch ID: ALPS06160806; Issue ID: ALPS06137462.

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 confidence

This vulnerability exists in the USB preloader component of MediaTek chipsets where proper image authentication is not enforced, allowing a physically present attacker to bypass permission checks and escalate privileges locally.

MitigationApply the vendor patch (ALPS06160806). Until patched, limit physical access to devices and disable USB debugging interfaces where possible.

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. Confirm MediaTek chipset is in use
    Check device specifications via Settings > About Phone > Chipset or use 'getprop ro.hardware' via ADB
    Affected if Device uses a MediaTek chipset and the bootloader/USB preloader is accessible
  2. Verify Android version matches affected releases
    Check Settings > About Phone > Android version or use 'adb shell getprop ro.build.version.release'
    Affected if Android version is 10.0, 11.0, or 12.0 on a MediaTek device
  3. Check USB debugging developer option status
    Go to Settings > Developer Options > USB debugging, or run 'adb get-state' to see if USB debugging is enabled
    Affected if USB debugging is enabled, allowing ADB access to the device
  4. Confirm USB preloader mode accessibility
    Attempt to enter MediaTek preloader mode via hardware key combination (Hold Vol Down + Connect USB) or check if 'adb reboot bootloader' exposes preloader interfaces
    Affected if USB preloader mode is accessible via hardware or ADB commands without authentication

A defender is affected if their device has a MediaTek chipset, runs Android 10.0, 11.0, or 12.0, and has USB debugging or preloader mode accessible, allowing a physically present attacker to bypass authentication and escalate privileges locally.
