CVE-2026-49906 →

📋 Description

An unprivileged application can bypass the android.car.permission.CAR_DISPLAY_IN_CLUSTER permission by registering an activity with the android.car.cluster.NAVIGATION category and requesting navigation app focus. The privileged ClusterHomeSample application, acting as a confused deputy, resolves and launches this arbitrary third-party activity on the safety-critical instrument cluster display without enforcing the necessary permission check, allowing for persistent display of potentially misleading or distracting content.
