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
Out-of-bounds read in parsing audio data in libsavsac.so prior to SMR Apr-2025 Release 1 allows local attackers to read out-of-bounds memory.

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

An out-of-bounds read vulnerability exists in libsavsac.so when parsing audio data. The flaw allows a local attacker to read memory beyond allocated buffer boundaries, potentially exposing sensitive information. This affects Samsung devices running versions prior to the SMR Apr-2025 Release 1.

MitigationApply the Samsung SMR Apr-2025 security update or later to remediate this vulnerability. Organizations should identify devices using the affected library version and prioritize patching based on their exposure model.

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. Check Android version
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB
    Affected if Version is 13.0, 14.0, or 15.0
  2. Verify libsavsac.so library presence
    Locate the file using 'find / -name libsavsac.so 2>/dev/null' via ADB shell, or check common paths like /vendor/lib/ or /system/lib/
    Affected if The library file exists on the device
  3. Check Samsung SMR version
    Run 'getprop ro.build.version.samsung' via ADB to retrieve the Samsung Maintenance Release version, or check Settings > About Phone > Software info > Security patch level
    Affected if SMR version is earlier than Apr-2025 Release 1 (typically shows as SMR-XXX-2025-04-01 or lower)
  4. Confirm audio parsing feature is active
    Check if the device uses Samsung audio processing by reviewing running processes containing 'savsac' via 'ps -A | grep -i savsac' or monitor audio playback activity
    Affected if The libsavsac.so library is actively loaded or used by system processes

The device is affected if it runs Android 13.0, 14.0, or 15.0, contains the libsavsac.so library, and has an SMR version earlier than Apr-2025 Release 1.

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

Apply the Samsung SMR Apr-2025 security update or later to remediate this vulnerability. Organizations should identify devices using the affected library version and prioritize patching based on their exposure model.

Recommended fix Moderate confidence

SMR Apr-2025 Release 1 or later

  1. Check for system software updates on your Samsung Galaxy device
  2. Go to Settings > Software Update > Download and Install
  3. Ensure the device is updated to SMR Apr-2025 Release 1 or later which contains the fix for CVE-2025-20944
  4. Verify the security patch level in Settings > About Phone > Software Information shows the April 2025 security update or later
