Last modified

CVE-2026-49903 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. 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.. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
