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
Use of implicit intent for sensitive communication in Configuration message prior to SMR Jul-2024 Release 1 allows local attackers to get sensitive information.

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 is a Samsung Android vulnerability in the Configuration message handling component. The application uses implicit intents (broadcasts without specifying an explicit target receiver) to transmit sensitive configuration data. A malicious local application can register an intent filter to intercept these implicit intents and capture the sensitive information before the intended receiver processes it.

MitigationSamsung has released the SMR Jul-2024 Release 1 patch. Users should apply the latest Samsung security update. For other affected Samsung devices, developers must refactor the Configuration message handling to use explicit intents (specifying the exact receiver component) instead of implicit intents for all sensitive communications.

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 Samsung Android device
    Check the device manufacturer and model by going to Settings > About Phone > Device name, or run 'getprop ro.product.brand' in ADB shell
    Affected if Device is not a Samsung-branded Android device (this CVE affects Samsung-specific implementation only)
  2. Check Android OS version
    Navigate to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' in ADB shell
    Affected if Android version is 12.0, 13.0, or 14.0 exactly (these are the affected versions)
  3. Verify Samsung security patch level
    Navigate to Settings > About Phone > Software information > Security patch level, or run 'getprop ro.build.version.samsung' in ADB shell to check the SMR date
    Affected if Security patch level is earlier than July 2024 SMR Release 1 (unpatched devices are vulnerable)
  4. Identify Configuration message handling
    For app developers: review source code for any usage of sendBroadcast() or similar intent-sending methods when transmitting sensitive configuration data between components
    Affected if Application code uses implicit intents (Broadcast intents without setComponent(), setPackage(), or explicit receiver specification) for sensitive configuration messages

A Samsung Android device running version 12.0, 13.0, or 14.0 with a security patch level earlier than July 2024 Release 1 is affected by this vulnerability.

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

Samsung has released the SMR Jul-2024 Release 1 patch. Users should apply the latest Samsung security update. For other affected Samsung devices, developers must refactor the Configuration message handling to use explicit intents (specifying the exact receiver component) instead of implicit intents for all sensitive communications.

Recommended fix High confidence

SMR Jul-2024 Release 1 (July 2024 security patch)

  1. Check your current Android security patch level in Settings > About Phone > Software Information > Security patch level
  2. Verify if your device has received the July 2024 security update (SMR Jul-2024 Release 1)
  3. If not available, check for system updates in Settings > Software Update > Download and install
  4. Apply the latest available Samsung security update containing the July 2024 patch level
  5. After updating, confirm the security patch level shows July 2024 or later
Caveat Security patches are generally backward-compatible; no expected breaking changes from applying monthly security updates
