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

Description The issue is related to a possible permanent denial of service (DoS) due to resource exhaustion in the setMediaButtonBroadcastReceiver function of MediaSessionRecord.java. This could lead to a local denial of service 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 setMediaButtonBroadcastReceiver function in MediaSessionRecord.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.
