Name of the Vulnerable Software and Affected Versions Android versions prior to Android-11 Android versions 8.1 through Android-10

Description The issue is related to a missing permission check in the startListening method of PluginManagerImpl.java. This could allow disabling arbitrary app components, leading to a local denial of service without requiring additional execution privileges. User interaction is not necessary for exploitation.

Recommendations For Android versions 8.1 through Android-10, consider restricting access to the PluginManagerImpl class until a patch is available. For Android versions prior to Android-11, update to a newer version to mitigate the risk. As a temporary workaround, consider disabling the startListening method of PluginManagerImpl.java to minimize the risk of exploitation.
