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

Description In the broadcastServiceStateChanged function of TelephonyRegistry.java, there is a possible way to learn base station information without location permission due to a missing permission check. This could lead to local information disclosure with User execution privileges needed. User interaction is not needed for exploitation.

Recommendations For Android versions Android-12 through Android-12L, consider restricting access to the TelephonyRegistry class until a patch is available. As a temporary workaround, review and restrict the use of the broadcastServiceStateChanged function to minimize the risk of exploitation.
