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 checkAccess of MediaProvider.java, there is a possible file deletion due to a path traversal error. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-11 Android-12 Android-12L Android-13Android ID: A-221855295

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

A path traversal vulnerability exists in the checkAccess function of MediaProvider.java on Android devices. The flaw allows an attacker to manipulate file paths to delete arbitrary files outside the intended MediaProvider sandbox, enabling local privilege escalation without requiring additional execution privileges or user interaction.

MitigationApply the Android security patch level for the affected Android versions (Android-11 through Android-13) which addresses the path traversal in MediaProvider. For enterprise deployments, ensure devices receive system updates containing the fix (September 2022 Android Security Bulletin or later).

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. Check Android OS version
    Open Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shell
    Affected if The version displayed is 11.0, 12.0, 12.1, or 13.0
  2. Check Android security patch level
    Navigate to Settings > About Phone > Security patch level, or run 'getprop ro.build.version.security_patch' via ADB
    Affected if The patch level is earlier than 2022-09-05 or is not set
  3. Verify MediaProvider is present
    Run 'pm list packages | grep android.providers.media' in ADB shell, or check /system/priv-app/MediaProvider exists on the device
    Affected if The MediaProvider package is installed (which is default on affected Android versions)

A device is affected if it runs Android 11.0, 12.0, 12.1, or 13.0 and has a security patch level earlier than the September 2022 Android Security Bulletin.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the Android security patch level for the affected Android versions (Android-11 through Android-13) which addresses the path traversal in MediaProvider. For enterprise deployments, ensure devices receive system updates containing the fix (September 2022 Android Security Bulletin or later).

Recommended fix Moderate confidence

Android 14 (or Android 13 with August 2022 security patch level)

  1. 1. Navigate to Settings on your Android device
  2. 2. Go to System > System Update (or Settings > About Phone > System Update)
  3. 3. Check for and install the latest Android security update
  4. 4. For full protection, upgrade to Android 14 or later which includes the complete fix for this vulnerability
  5. 5. Verify the security patch level is August 2022 or later by going to Settings > About Phone > Android Version and checking the Security patch level
