AI Analysis

Impact

The vulnerability in MediaTek’s MiracastService is a classic confused deputy flaw (CWE‑926). An adversary can trigger an escalation of privilege that leads to a local denial of service. The attack requires only user‑level execution rights and does not need any explicit user interaction. Once triggered, the service can be forcibly stopped, disrupting device functionality for the user.

Affected Systems

The flaw affects MediaTek, Inc. chipset devices that run MiracastService. No specific version numbers are provided, but patch IDs ALPS11060069 and DTV04881615 indicate that affected firmware releases are currently being addressed by MediaTek.

Risk and Exploitability

The risk is local, as exploitation requires the attacker to already have user privileges on the device. No user interaction is required, making the attack feasible for anyone with device access. EPSS data is not available, and the vulnerability is not listed in the CISA KEV catalog. The CVSS score of 5.5 indicates a moderate severity; despite this, the potential for a local denial of service with no user involvement suggests that the vulnerability remains a significant concern for device integrity.

OpenCVE Recommended Actions

  • Apply the MediaTek patch identified by ALPS11060069 / DTV04881615 on all affected devices.
  • If a patch is not immediately available, disable the MiracastService component to prevent the privilege escalation from being exercised.
  • Restrict device user accounts to the minimum privileges required for normal operation to limit the scope of any denial of service that may occur.
