CVE-2026-58930

Published Nov 2, 2026 CVSS 3.1 · 7.8 High EPSS < 1% KEV · Not listed
Description
An unprivileged application can exploit a lack of package/signature validation in SystemUI's `RemoteQCController` when resolving a hardcoded `content://` URI. This allows the attacker to squat on a specific authority if the legitimate package is absent, inject spoofed UI elements into the trusted SystemUI Quick Controls panel, and gain a Background Activity Launch (BAL) grant from SystemUI when the user interacts with the spoofed element.
