Detailsinfo

A vulnerability has been found in Google Android 14/15/16/16-qpr2/17 and classified as problematic. This vulnerability affects an unknown part of the component PassengerKeyguard. The manipulation with an unknown input leads to a improper authorization vulnerability. The CWE definition for the vulnerability is CWE-285. The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

A physical occupant on an Android Automotive OS (AAOS) Multi-User Multi-Display (MUMD) passenger display can view sensitive Heads-Up Notification (HUN) content and execute actions for a secure passenger user (User N) without authenticating. This bypasses the PassengerKeyguard because the HUN system only checks the global keyguard state, which is tied to the driver's unlocked display, and the PassengerKeyguard implementation fails to suppress HUNs or intercept action PendingIntents. Consequently, private notification data is disclosed, and user-N actions are executed without credential verification.
