Name of the Vulnerable Software and Affected Versions Android version Android-11

Description The issue is related to a missing permission check in the createInputConsumer function of WindowManagerService.java. This could allow an attacker to block and intercept input events, potentially leading to local escalation of privilege without needing additional execution privileges. User interaction is required for exploitation.

Recommendations For Android version Android-11, consider restricting access to the createInputConsumer function of WindowManagerService.java until a patch is available. As a temporary workaround, avoid using the affected function to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
