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 multiple functions of MmsProvider.java, there is a possible way to arbitrarily delete files which affect telephony, SMS, and MMS functionalities due to a path traversal error. This could lead to local denial of service 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 · high confidence

A path traversal vulnerability exists in multiple functions of MmsProvider.java in Android's MMS provider component. The vulnerability allows arbitrary file deletion through directory traversal sequences (e.g., ../) without proper path validation. This can delete critical telephony, SMS, and MMS system files, causing local denial of service without requiring elevated privileges or user interaction.

MitigationApply proper input validation and path canonicalization in all affected MmsProvider.java functions to prevent path traversal sequences. Validate that resolved file paths stay within expected directories before performing file operations.

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 version
    Run 'getprop ro.build.version.release' or check Settings > About Phone > Android version
    Affected if The version is exactly 14.0, 15.0, or 16.0
  2. Verify MmsProvider component accessibility
    Check if any third-party or non-system apps have permission to access the MMS provider by reviewing app manifest permissions and running 'dumpsys package <package_name>' for packages with android.permission.READ_MMS or android.permission.WRITE_MMS
    Affected if Apps without system privileges can access or query MmsProvider
  3. Review system logs for path traversal attempts
    Run 'logcat -d | grep -i "../"' or search logcat for MmsProvider and directory traversal patterns like '../' or '..\'
    Affected if Logs show suspicious ../ sequences in MMS provider queries or file operations
  4. Verify integrity of telephony and MMS system files
    Check for existence of critical files in /data/data/com.android.phone/, /system/data/com.android.mms/, or similar telephony/MMS directories by running 'ls -la' on these paths
    Affected if Critical telephony, SMS, or MMS system files are missing or were unexpectedly deleted
  5. Check for abnormal file deletion events
    Review audit logs (if enabled) or logcat for MmsProvider file deletion operations using 'logcat -d | grep -i "MmsProvider" | grep -i delete'
    Affected if File deletion operations from MmsProvider are logged for files outside the expected MMS data directory

You are affected if your Android device runs version 14.0, 15.0, or 16.0 AND the MMS provider is accessible to apps without elevated system privileges, or if logs show path traversal attempts or unexpected file deletions.
