Unisoc Modem Vulnerability: Millions of Android Devices at Risk
In August 2026, researchers at SSD Secure Disclosure identified a critical security vulnerability in Unisoc's T612 modem firmware. By chaining a previously disclosed remote code execution (RCE) flaw with a newly discovered memory isolation weakness, attackers can gain privileged access to the Android kernel on affected devices. The exploit involves delivering a malicious payload to the modem and then initiating a video call, which the victim must answer to trigger the attack. This vulnerability impacts devices from manufacturers such as Realme, Xiaomi, and Motorola, leaving millions of users at risk. The significance of this discovery lies in the increasing prevalence of sophisticated attack chains targeting mobile devices. As threat actors continue to exploit firmware-level vulnerabilities, it underscores the necessity for robust security measures and timely firmware updates to protect user data and device integrity.
