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
In isSameApp of NotificationManagerService.java, there is a possible persistent dos due to resource exhaustion. This could lead to local denial of service with no additional execution privileges needed. User interaction is not needed for exploitation.

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

A resource exhaustion vulnerability exists in the isSameApp function of Android's NotificationManagerService.java. The function, which likely validates whether notifications originate from the same application, fails to properly limit or validate resource consumption, allowing an attacker to cause persistent denial of service without any special privileges or user interaction.

MitigationOrganizations should apply Android system updates from OEMs once available, as this is a framework-level vulnerability requiring AOSP patch integration. Until the patch is available, monitor notification traffic for abnormal patterns that could indicate exploitation.

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
    Run 'getprop ro.build.version.release' in a terminal or check Settings > About Phone > Android version
    Affected if The version is 14.0, 15.0, or 16.0
  2. Verify build fingerprint or security patch level
    Run 'getprop ro.build.fingerprint' or check Settings > About Phone > Security Patch Level to confirm the exact Android build
    Affected if The device is running an affected Android 14, 15, or 16 build without the corresponding vendor fix
  3. Check if NotificationManagerService is accessible
    Verify the system service is running by examining process list with 'ps -A | grep notification' or checking system service registry via 'dumpsys notification'
    Affected if The NotificationManagerService is active on the device (standard state for Android devices)
  4. Monitor for resource exhaustion indicators
    Use 'dumpsys meminfo' or check system logs via 'logcat -d' for repeated notification-related errors, high CPU usage by system_server, or notification queue buildup
    Affected if Abnormal resource consumption patterns in notification system without other expla­nation

The device is affected if it runs Android 14.0, 15.0, or 16.0 without the vendor-specific security patch that addresses the NotificationManagerService isSameApp resource exhaustion vulnerability.

Mitigation

Organizations should apply Android system updates from OEMs once available, as this is a framework-level vulnerability requiring AOSP patch integration. Until the patch is available, monitor notification traffic for abnormal patterns that could indicate exploitation.

Recommended fix Moderate confidence

Latest Android Security Patch Level (monthly updates containing CVE-2025-48648 fix)

  1. Check your device's current Android Security Patch Level in Settings > About Phone > Android version
  2. Apply the latest Android system update available for your device (which includes the latest Android Security Bulletin patches)
  3. For Pixel devices, ensure you have the latest monthly security update installed
  4. For other manufacturers, check with your device manufacturer or carrier for the latest security patch update that addresses this vulnerability
Caveat Security updates typically have minimal risk; may require device restart to fully apply protections
