Cross-user image leak in Android PrintManagerService

IdentifiersCVE-2025-48628CWE-441· Unintended Proxy or Intermediary…

CVE-2025-48628 is an Android Framework information-disclosure vulnerability in PrintManagerService.java, specifically in the validateIconUserBoundary logic. According to the provided content, the flaw is caused by a confused deputy condition that can result in a cross-user image leak. In practice, this means the service can be induced to access or expose image data across Android user boundaries in a way that violates intended isolation. The issue does not require user interaction for exploitation and is described as enabling local escalation of privilege in the sense that an unprivileged local actor can obtain access beyond normal app or user-boundary restrictions.

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 image data across Android user profiles or user boundaries, undermining Android's multi-user isolation model. The provided content characterizes the issue as a local escalation of privilege with no additional execution privileges needed, meaning a local attacker operating from a low-privilege context may gain access to data or capabilities not normally available to that context. The primary concrete impact described in the content is cross-user information exposure.

Mitigation

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

If immediate patching is not possible, reduce exposure by limiting installation and execution of untrusted local applications, especially on shared or multi-user Android devices where cross-user boundary violations have greater impact. Prefer fully managed device configurations, minimize use of multiple user profiles where operationally feasible, and accelerate deployment of OEM firmware updates aligned with the December 2025 Android bulletin. However, no complete mitigation is provided in the content aside from applying the vendor patch.

Remediation

Patch, then assume compromise.

Apply the Android security updates that include the fix for CVE-2025-48628. The provided content places this issue in Google's December 2025 Android Security Bulletin and indicates that devices updated to the 2025-12-05 patch level are fully remediated for issues disclosed in that bulletin. Enterprises should ensure OEM and vendor-provided updates incorporating the December 2025 Android fixes are deployed to affected supported devices.
