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 insufficiently random values in Auracast prior to SMR Mar-2025 Release 1 allows adjacent attackers to access Auracast broadcasting.

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

Auracast implementations prior to SMR Mar-2025 Release 1 use insufficiently random values in their broadcast functionality. This randomness weakness allows an adjacent attacker within Bluetooth range to predict or derive the values used for broadcast access, enabling unauthorized access to what should be private Auracast broadcasts.

MitigationUpdate Auracast firmware/software to SMR Mar-2025 Release 1 or later to obtain the properly random values. Organizations should inventory Auracast deployments and prioritize updating devices that handle sensitive audio broadcasts.

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
    Go to Settings > About Phone > Android version and confirm it reads 14.0 or 15.0
    Affected if Android version is 14.0 or 15.0 on a Samsung device
  2. Check Samsung Maintenance Release (SMR) version
    Go to Settings > About Phone > Software information > Build number; the SMR version appears in the format SMRx-xxxx (for example, SMR1-xxxx)
    Affected if SMR version is before SMR3-2025 (March 2025 Release 1) or cannot be confirmed as SMR Mar-2025 Release 1 or later
  3. Confirm Auracast functionality is in use
    Check Settings > Connected devices > Auracast or look for Auracast listener/broadcast options in the Bluetooth or quick settings panel
    Affected if Auracast broadcasts are enabled or the device has acted as an Auracast source or listener
  4. Identify Auracast broadcast configuration
    Review Bluetooth sharing settings or any Auracast-specific settings to determine if private or sensitive audio broadcasts are configured
    Affected if Private Auracast broadcasts are active and the device runs the affected Android/SMR combination

A user is affected if their Samsung Android device runs version 14.0 or 15.0 with a Samsung Maintenance Release prior to March 2025 Release 1 AND they have Auracast broadcast functionality enabled or have configured private Auracast broadcasts.

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

Update Auracast firmware/software to SMR Mar-2025 Release 1 or later to obtain the properly random values. Organizations should inventory Auracast deployments and prioritize updating devices that handle sensitive audio broadcasts.

Recommended fix High confidence

SMR Mar-2025 Release 1 (March 2025 Security Patch Level)

  1. Open Settings on the Samsung device
  2. Navigate to Security and privacy > Security update
  3. Tap on Check for updates to search for the March 2025 security update
  4. Download and install the SMR Mar-2025 Release 1 update if available
  5. Restart the device to complete the installation
  6. Verify the update was applied by checking Settings > Security and privacy > Security update - the security patch level should show March 2025
