AI Threat Summary

CVE-2026-70380 is a moderate vulnerability with a CVSS score of 5.3 affecting the target software. Authentication can be bypassed allowing unauthenticated access. Threat hunters should monitor for exploit attempts and apply vendor patches immediately.

Description

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.
