Unprivileged Application Vulnerability in Android SystemUI's RemoteQCController

CVE-2026-58930

What is CVE-2026-58930?

A vulnerability exists in Android's SystemUI related to the RemoteQCController component, where an unprivileged application can take advantage of inadequate package and signature validation. By leveraging a hardcoded 'content://' URI, attackers can impersonate a legitimate authority, allowing them to inject misleading UI elements into the trusted Quick Controls panel. This interaction could lead to a Background Activity Launch (BAL) grant, posing significant security risks as users might unknowingly engage with these spoofed components.
