CVE-2026-58930: Android SystemUI signature validation bypass in RemoteQCController

CVE-2026-58930 · Severity: info · Published 2026-11-02

Android's SystemUI component, which manages the vehicle's user interface in automotive systems, fails to validate package signatures when resolving Quick Control panel content. An unprivileged application can exploit this to inject fake UI elements into the trusted Quick Controls panel and gain permission to launch background activities when users interact with the spoofed elements.

Technologies: Google Android, Google Android Automotive OS. Vendors: Google.

Technical details

The vulnerability is an elevation of privilege (EOP) in SystemUI's RemoteQCController that lacks package and signature validation when resolving a hardcoded content:// URI. An unprivileged attacker can squat on the authority when the legitimate package is absent, inject spoofed UI elements, and obtain a Background Activity Launch grant when the user interacts with the fake element. The attack requires no special privileges or user interaction beyond normal interaction with the spoofed Quick Controls.
