Recommendation: Monitor — no exploitation signal at the moment.

In multiple functions of KeyguardViewMediator.java, there is a possible way to bypass lockdown mode with screen pinning due to a logic error in the code. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.
