CVE-2025-48563
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 · uneditedIn onNullBinding of RemoteFillService.java, there is a possible background activity launch due to an insecure default value. This could lead to local escalation of privilege 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 confidenceThis is a local privilege escalation vulnerability in Android's RemoteFillService where an insecure default value in the onNullBinding method allows unauthorized background activity launches without user interaction or additional execution privileges.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify Android versionRun 'adb shell getprop ro.build.version.release' or check Settings > About Phone > Android versionAffected if The version shown is 13.0, 14.0, 15.0, or 16.0 exactly (not a later patch version)
-
Check security patch levelRun 'adb shell getprop ro.build.version.security_patch' or check Settings > About Phone > Security patch levelAffected if The security patch level is earlier than the patch that fixes this CVE in RemoteFillService (if unknown, assume affected if version matches)
A device is affected if it runs Android 13.0, 14.0, 15.0, or 16.0 and has not received the security update that patches the onNullBinding insecure default in RemoteFillService.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply the Android security patch that addresses this vulnerability in RemoteFillService.java; users should ensure their devices receive the latest system updates.
Android 16 with latest 2025 security patch level (or Android 15/14 with respective latest security updates)
- Check the Android Security Bulletin for the month containing CVE-2025-48563 to identify the required Security Patch Level (SPL)
- Apply the latest available Android system update for your device model that includes the security fix
- For Android 13.0: Ensure the device receives the 2025-06-01 or later security patch level
- For Android 14.0: Ensure the device receives the 2025-06-01 or later security patch level
- For Android 15.0: Ensure the device receives the 2025-06-01 or later security patch level
- For Android 16.0: Ensure the device receives the 2025-06-01 or later security patch level
- Verify the patch level by going to Settings > About Phone > Android version or Security patch level
- If no update is available from your device manufacturer, consider upgrading to a device with newer Android version support
