Description The issue is related to a logic error in the getUserCount and getCount methods of UserSwitcherController.java. This error could allow for the creation of new users, potentially leading to local escalation of privilege. An attacker with physical access to the device can exploit this issue without needing additional execution privileges. User interaction is not required for exploitation.
