ZERO-CLICK DoS: The Unpatched Unisoc Modem Flaw Crashing Androids (CVE-2025-6161 #cybersecurity

Fellow defenders and users, in the critical interest of Coordinated Vulnerability Disclosure (CVD), this security briefing analyzes CVE-2025-61613, a high-severity (CVSS v3.1 base score of 7.5) vulnerability discovered in the nr modem
. This improper input validation flaw allows adversaries to execute a remote denial of service (DoS), resulting in a complete system crash

A highly exploitable, zero-click network vulnerability currently threatens Android devices utilizing Unisoc modems, allowing adversaries to trigger a remote system crash with no privileges required—and concerningly, there is currently no official patch or workaround provided by the vendor
. The attack vector operates directly over the network with low complexity, demanding absolutely no user interaction or elevated privileges to achieve a successful exploit
. Furthermore, the CISA ADP Vulnrichment assessment confirms this vulnerability's exploitation is fully 'automatable'

🚨 Affected Infrastructure: If your environment utilizes Google Android versions 13.0, 14.0, 15.0, or 16.0 paired with vulnerable Unisoc chipsets (specifically the T8100, T8200, T8300, and T9100), your systems are at risk

🛡️ Immediate Mitigation Strategies: Because the vendor has not yet supplied an official patch or workaround, immediate awareness is our strongest shield
. Security teams must act now to enforce interim protective measures
. We urge organizations to implement strict access control policies, actively monitor network traffic for anomalous inputs directed at modem interfaces, and prepare your infrastructure for rapid patch deployment the exact moment firmware updates are released by Unisoc and Google

Stay vigilant, monitor your endpoints, and protect your networks.
