**Deck**: Security researchers have disclosed an exploit chain in Unisoc-based Android phones that uses a VoLTE video call over attacker‑controlled 4G infrastructure to gain full kernel access — with no patch yet available. The bug turns everyday cellular calls into a potential entry point for deep compromise, raising stakes for millions of budget and mid‑range device users and the networks that carry their traffic.

A newly disclosed security flaw in a popular mobile chipset line has turned a routine voice call into a potential route for total device takeover, and there is not yet a fix. Researchers have revealed a Voice over LTE (VoLTE) exploit chain affecting Android phones built on Unisoc modems that can give an attacker full access to the Android kernel — the core of the operating system that controls everything from app permissions to memory and hardware. The chain begins with a remote code execution (RCE) vulnerability in the modem itself and then allows malicious modem code to modify Android kernel memory, effectively handing an intruder the keys to the…
