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
On Samsung mobile devices with N(7.x) software, attackers can install an arbitrary APK in the Secure Folder SD Card area because of faulty validation of a package signature and package name, aka SVE-2017-10932.

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 · moderate confidence

On Samsung mobile devices running Android N (7.x), a vulnerability in the Secure Folder feature allowed attackers to install arbitrary APK files in the Secure Folder SD Card area due to insufficient validation of package signatures and package names. This bypassed the intended security boundaries of the Secure Folder, which is designed to isolate sensitive applications and data.

MitigationApply the vendor security patch released by Samsung for this vulnerability (SVE-2017-10932). Users should ensure their devices are running the latest available Samsung security updates.

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. Verify Android version is 7.x
    Go to Settings > About Phone > Android version. Confirm the version is exactly 7.0, 7.1, 7.1.1, or 7.1.2
    Affected if Android version is 7.0, 7.1, 7.1.1, or 7.1.2 on a Samsung device
  2. Confirm device is Samsung
    Check the device manufacturer. Go to Settings > About Phone > Device name or manufacturer. Samsung devices are affected; other manufacturers are not in scope for this CVE
    Affected if Device is made by Samsung and runs Android 7.x versions listed above
  3. Check if Secure Folder is present
    Look for Secure Folder app on the device. On Samsung devices running Android N, Secure Folder is typically found in Settings > Biometrics and security > Secure Folder, or search for 'Secure Folder' in the app drawer
    Affected if Secure Folder feature exists and is accessible on the device (vulnerability requires Secure Folder to be present)
  4. Verify Samsung security patch level
    Go to Settings > About Phone > Security patch level. Check if the installed security updates are dated after the SVE-2017-10932 patch release. The patch was released by Samsung to address this specific vulnerability
    Affected if Security patch level is earlier than the SVE-2017-10932 fix or the device has not received Samsung's security update for this vulnerability

A Samsung device is affected if it runs Android 7.0-7.1.2, has the Secure Folder feature, and lacks the vendor security patch addressing SVE-2017-10932
