Vulnerability from github – Published: 2026-11-02 21:32 – Updated: 2026-11-02 21:32

Details

The ClusterRenderingService.dump() method, accessible to processes holding android.permission.DUMP and android.permission.PACKAGE_USAGE_STATS, acts as a confused deputy. It allows attackers to write arbitrary values to Settings.Global.OVERLAY_DISPLAY_DEVICES, an operation normally requiring android.permission.WRITE_SECURE_SETTINGS, enabling persistent creation of system overlay displays and injection of key events into the cluster UI.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
