Google is considering a change that would limit the Android Debug Bridge daemon (ADBD) to only the wlan0 network interface, effectively blocking on-device (loopback) ADB connections. This would affect tools such as Shizuku, libadb‑android, and App Manager that rely on local ADB access. The move aims to close a potential attack vector where malicious apps could exploit enabled developer settings and remote ADB, but it also threatens the workflow of developers and power users who depend on on‑device debugging for app development and system customization. The proposed restriction stems from CVE‑2026‑0073 and would bind ADBD to the wlan0 interface only, breaking loopback (127.0.0.1) ADB used by many open‑source power‑user apps. Developers could work around it by using a VPN or tethering, but the change would require re‑configuring existing tooling.
