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 handleMessage of UsbDeviceManager.java, there is a possible method to access device contents over USB without unlocking the device due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

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
How this class of weakness works · CWE-276

Files, directories, or resources ship with permissions more open than they need to be, so unintended users can read or modify them. Attackers look for exactly these loose defaults. Remediation means tightening permissions to the minimum required and verifying them at install and at runtime.

General guidance for the incorrect default permissions class — the official description and references above are authoritative for this specific CVE. Want a bespoke review and a reviewed fix? Ask our team →

Recommended fix High confidence

Android 15 (or latest stable release with December 2024 security patch level or later)

  1. 1. Verify the current Android version on the device by going to Settings > About Phone > Android version
  2. 2. Check if an Android security update is available by going to Settings > Security > Security update > Check for update
  3. 3. If available, install the latest Android security patch level that addresses CVE-2024-43085
  4. 4. For affected versions (Android 12.0, 12.1, 13.0, 14.0), update to Android 15 or the latest stable release which contains the fix
  5. 5. After updating, verify the USB debugging and USB file transfer settings are set to require device unlock in Settings > Developer options > USB debugging
Caveat Android 15 introduces UI and behavioral changes; ensure compatibility testing with existing apps before mass deployment
