Android Framework companion device disassociation privilege escalation in DisassociationProcessor.java

IdentifiersCVE-2025-48525CWE-20· Improper Input Validation

CVE-2025-48525 is an Android Framework elevation-of-privilege vulnerability in the companion device disassociation logic, specifically in disassociate handling within DisassociationProcessor.java. According to the provided description, improper input validation can allow an application to continue reading notifications even after it is no longer associated with a companion device. This indicates a failure to correctly enforce state and authorization checks during or after disassociation, resulting in unauthorized retention of notification access. The issue is classified as a local privilege escalation vulnerability and does not require user interaction for exploitation.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a local application to retain and use notification-reading capabilities after companion device association has been removed. This can result in unauthorized access to notification content and associated sensitive information, and constitutes a local escalation of privilege because the app can continue exercising capabilities it should no longer possess. No additional execution privileges are required, increasing the practical risk from a malicious installed app.

Mitigation

If you can’t patch tonight, do this now.

Until patches are deployed, reduce exposure by limiting installation of untrusted applications, especially apps requesting or previously granted companion-device-related capabilities or notification access. Review and revoke unnecessary notification access and companion device associations where possible, and use enterprise controls to restrict sideloading and unapproved apps. However, definitive mitigation is patching, because the flaw does not require user interaction once a malicious local app is present.

Remediation

Patch, then assume compromise.

Apply the Android security update that includes the fix for CVE-2025-48525. The provided context places this issue in Google’s December 2025 Android Security Bulletin, and devices updated to the 2025-12-05 patch level are described as fully remediated for disclosed issues in that bulletin. OEMs and enterprises should ensure affected Android 13–16 devices receive the corresponding platform and vendor updates as applicable.
