CVE-2026-49903

MediumCVSS 5.5/10Last modified Nov 10, 2026

Description

The `ClusterRenderingService.dump()` method, accessible to processes holding `android.permission.DUMP` and `android.permission.PACKAGE_USAGE_STATS`, acts as a confused deputy. It allows attackers to write arbitrary values to `Settings.Global.OVERLAY_DISPLAY_DEVICES`, an operation normally requiring `android.permission.WRITE_SECURE_SETTINGS`, enabling persistent creation of system overlay displays and injection of key events into the cluster UI.
