CVE-2025-61616
Published: 09 March 2026
Summary
CVE-2025-61616 is a high-severity Improper Input Validation (CWE-20) vulnerability in Google Android. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 26.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SC-5 (Denial-of-service Protection) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2025-61616 is a vulnerability in the nr modem component, stemming from improper input validation (CWE-20). This flaw can cause a system crash, enabling a remote denial of service (DoS). It affects Unisoc's nr modem implementations, with a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating high severity due to its network-accessible nature and complete lack of prerequisites for exploitation.
A remote attacker requires no authentication or privileges to exploit this vulnerability over the network with low complexity. By sending malformed input to the nr modem, the attacker can trigger a system crash, resulting in a denial of service that disrupts availability without impacting confidentiality or integrity.
Unisoc has issued an announcement detailing the issue at https://www.unisoc.com/en/support/announcement/2030931350138310657, which security practitioners should consult for mitigation guidance, such as applying vendor patches or workarounds. The vulnerability was published on 2026-03-09.
