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
An issue was discovered on Samsung mobile devices with KK(4.4), L(5.0/5.1), M(6.0), and N(7.0) software. An attacker can obtain the full pathnames of sdcard files by reading the system protected log upon reception of a certain intent. The Samsung ID is SVE-2016-7183 (January 2017).

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 information disclosure vulnerability in Samsung mobile devices (Android KK 4.4 through N 7.0) allows an unprivileged application to obtain full pathnames of files on the sdcard by reading system-protected logs that are populated upon reception of a specific Android intent. The attacker does not require special permissions to read this protected log entry.

MitigationDeploy Samsung firmware updates containing the SVE-2016-7183 patch to affected devices. For enterprise fleets, verify device patch levels through mobile device management (MDM) tooling and ensure compliance with organizational patch policies.

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 device is a Samsung mobile device
    Check the device manufacturer and model through Settings > About Phone > Manufacturer or by running 'getprop ro.product.manufacturer' via ADB
    Affected if The device is not manufactured by Samsung
  2. Check the Android OS version
    Navigate to Settings > About Phone > Android version or run 'getprop ro.build.version.release' via ADB
    Affected if The Android version is 4.4, 5.0, 5.1, 6.0, or 7.0
  3. Verify Samsung patch level for CVE-2017-18687
    Check Settings > About Phone > Security patch date or run 'getprop ro.build.version.security_patch' via ADB. The patch was released as part of Samsung SVE-2016-7183
    Affected if The security patch level is earlier than the Samsung update containing SVE-2016-7183, or the patch date cannot be verified
  4. Confirm log access vulnerability exists
    This requires examining whether an unprivileged application can read system-protected log entries generated by the specific Android intent. Without the patch, logs accessible via 'logcat' or the RingBuffer API may contain sdcard path information that should be restricted
    Affected if Unprivileged apps can read system-protected log entries containing file path information

A Samsung mobile device running Android 4.4 through 7.0 without the SVE-2016-7183 patch is affected by this information disclosure vulnerability.
