Name of the Vulnerable Software and Affected Versions Android versions Android-11 through Android-13

Description The issue arises from uncaught exceptions in job map parsing within several methods of JobStore.java, potentially leading to a local persistent denial of service. This can occur without additional execution privileges and does not require user interaction for exploitation.

Recommendations For Android versions Android-11 through Android-13, consider restricting access to the JobStore.java methods until a patch is available. As a temporary workaround, avoid using the job map parsing functionality in JobStore.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.
