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
Improper access control vulnerability in TelephonyUI prior to SMR Aug-2023 Release 1 allows local attacker to connect BLE without privilege.

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

Improper access control in Samsung's TelephonyUI component allows a local attacker to connect to Bluetooth Low Energy (BLE) devices without proper privileges. The vulnerability exists in versions prior to the SMR Aug-2023 security update and stems from insufficient authorization checks before allowing BLE connections.

MitigationApply the Samsung SMR August-2023 security update (or later) to affected Galaxy devices to remediate this improper access control issue.

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 Android device
    Go to Settings > About Phone > Device name or manufacturer. Verify the manufacturer is Samsung.
    Affected if Device is not a Samsung Android device (this CVE only affects Samsung devices)
  2. Check Android version
    Navigate to Settings > About Phone > Android version. Confirm the installed Android version is 13.0.
    Affected if Android version is 13.0 (this is the affected version per the CVE)
  3. Check Samsung security patch level (SMR version)
    Navigate to Settings > About Phone > Software information > Security patch level. Look for the SMR (Samsung Monthly Report) date.
    Affected if Security patch level is earlier than August 2023 (SMR Aug-2023 or later contains the fix)
  4. Verify TelephonyUI component presence
    This check requires examining system logs or using a device diagnostics tool. In Settings > About Phone > Software information, confirm the build number includes the SMR patch date.
    Affected if Build does not reflect the August 2023 SMR update, indicating TelephonyUI remains unpatched

User is affected if they have a Samsung Android 13.0 device with a security patch level before August 2023, as the improper access control in TelephonyUI allowing unauthorized BLE connections has not been fixed.

Mitigation

Apply the Samsung SMR August-2023 security update (or later) to affected Galaxy devices to remediate this improper access control issue.

Recommended fix High confidence

SMR Aug-2023 Release 1 (Security Patch Level August 2023)

  1. Check your Samsung device model and current Android/Security Patch Level via Settings > About Phone > Software Information
  2. Navigate to Settings > Software Update
  3. Tap 'Download and install' to check for available updates
  4. Ensure the device updates to SMR Aug-2023 Release 1 or later which contains the fix for CVE-2023-30698
  5. Alternatively, manually verify via Settings > About Phone > Software Information that the Security Patch Level is August 2023 or newer
Caveat Samsung monthly security updates generally have minimal risk; ensure device is charged and connected to WiFi before updating
