CVE-2022-20234

Notification disclosure via spoofed permission confirmation

Published Jul 13, 2022 · Updated Aug 3, 2024

Information disclosure in Google Android Automotive OS 12L allows local users to read notifications through a deceptive permission prompt. The exported NotificationAccessConfirmationActivity trusts a supplied component name and package title, allowing a benign title to conceal a malicious component. A user must approve the spoofed confirmation; the malicious app then gains notification access and can read all notifications, including personal information.
