# Miracast MICE service: unauthenticated network denial of service on connection capacity

The Miracast over Infrastructure Connection Establishment (MICE) service can be overwhelmed by an unauthenticated attacker on the network, exhausting connection capacity. While the condition lasts, legitimate devices cannot set up MICE-based Miracast connections.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether MICE is enabled on the device, which the sources say is off by default; the sources do not name a setting or command.
- Check whether WLAN runs in Infrastructure mode on devices that use Miracast, since the sources say full disruption can occur in that mode.

## From the sources

A denial-of-service vulnerability has been identified in the Miracast over Infrastructure Connection Establishment (MICE) service. An unauthenticated attacker with network access to the MICE service could consume available connection capacity, preventing legitimate users from establishing MICE-based Miracast connections while the condition persists.
Miracast P2P is not affected. MICE is disabled in the default configuration and must be explicitly enabled by the customer. On most devices, Miracast P2P is available independently of MICE, but a complete disruption of Miracast can occur on some devices when WLAN is configured for Infrastructure mode.
