Name of the Vulnerable Software and Affected Versions Android versions prior to the fixed version

Description The issue allows an attacker to determine whether an app is installed without query permissions due to a missing permission check in Device Policy. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not required for exploitation.

Recommendations For Android versions prior to the fixed version, consider restricting access to the Device Policy feature to minimize the risk of exploitation until a patch is available.
