Name of the Vulnerable Software and Affected Versions Android versions Android-12

Description The issue is related to a side channel information disclosure in the onResume method of NotificationAccessDetails.java. This could allow an attacker to determine whether an app is installed without requiring query permissions, potentially leading to local information disclosure. No additional execution privileges are needed, and user interaction is not required for exploitation.

Recommendations For Android version Android-12, consider restricting access to sensitive information until a patch is available. As a temporary workaround, review and limit the use of the onResume method in NotificationAccessDetails.java to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
