CVE-2026-58915: Android Automotive OS Heads-Up Notification disclosure in MUMD

CVE-2026-58915 · Severity: info · Published 2026-11-02

Android Automotive OS multi-user multi-display systems allow a physical occupant to view sensitive notifications and trigger actions for a secure passenger user without authentication. This bypasses the passenger keyguard protection and can expose private notification data and enable unauthorized user actions, creating a privacy and security risk for multi-occupant vehicles.

Technical details

The Heads-Up Notification (HUN) system in Android Automotive OS checks only the global keyguard state (driver's unlock status) rather than the per-user PassengerKeyguard, allowing physical access to intercept HUN content and pending intents. An attacker with physical access to a passenger display can view and act on notifications meant only for an authenticated user. The vulnerability affects Android 14, 15, 16, 16-qpr2, and 17.

Affected products
