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

Description The issue is related to a missing bounds check in the onMulticastListUpdateNotificationReceived function of UwbEventManager.java, which could lead to arbitrary code execution. This might result in local escalation of privilege without requiring additional execution privileges. User interaction is not necessary for exploitation.

Recommendations For Android version Android-13, consider restricting access to the onMulticastListUpdateNotificationReceived function of UwbEventManager.java until a patch is available. As a temporary workaround, disabling the onMulticastListUpdateNotificationReceived function could help minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
