IdentifiersCVE-2025-48555CWE-441· Unintended Proxy or Intermediary…

CVE-2025-48555 is an Android System information-disclosure vulnerability in multiple functions of NotificationStation.java. According to the provided description, the issue is caused by a confused deputy condition that can result in cross-profile information disclosure. A local attacker can abuse NotificationStation functionality to access information across Android profile boundaries that should not be exposed to the attacking context. The vulnerability does not require user interaction and can be exploited without any additional execution privileges beyond those already available to the local attacker.

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 can disclose sensitive information across Android user/profile boundaries, undermining profile isolation. The provided description also states this can lead to local escalation of privilege, indicating an attacker may gain access to data or capabilities normally restricted to another profile or security context. The primary verified impact from the supplied content is unauthorized cross-profile information disclosure.

Mitigation

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

Until patches are deployed, reduce exposure by limiting installation of untrusted local applications, especially on devices using work/personal profile separation or other multi-profile configurations. Prioritize patching managed Android 13–16 devices to the December 2025 security level or vendor-equivalent update. Where possible, enforce enterprise app allowlisting and minimize local app execution from untrusted sources.

Remediation

Patch, then assume compromise.

Apply the Android security updates that include the fix for CVE-2025-48555. The provided bulletin context indicates that devices updated to the 2025-12-05 Android security patch level are fully remediated for issues disclosed in that bulletin, including Android System vulnerabilities such as this one. OEM and vendor-integrated updates should also be applied where applicable.
