addresses: CWE-20

Security testing and evaluation at multiple SDLC stages directly detects missing or flawed input validation, with the required remediation process ensuring fixes are applied.

addresses: CWE-20

Directly implements checks on information inputs to reject invalid data before processing.

addresses: CWE-20

Spam protection mechanisms perform filtering and detection on inbound/outbound messages, directly compensating for missing or weak input validation of unsolicited content.

MITRE ATT&CK Enterprise TechniquesAI

T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

Improper input validation in modem enables remote unauthenticated exploitation causing endpoint DoS (availability impact only).

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

In modem, there is a possible improper input validation. This could lead to remote denial of service with no additional execution privileges needed..

Deeper analysisAI

CVE-2025-61611 is an improper input validation vulnerability in the modem component, as described in its NVD entry published on 2026-03-09. The flaw, mapped to CWE-20 (Improper Input Validation) and noted with NVD-CWE-noinfo, carries 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). It affects modem implementations, with a vendor advisory published by Unisoc.

The vulnerability enables a remote denial of service attack with no additional execution privileges required. An unauthenticated attacker on the network can exploit it with low attack complexity and no user interaction, achieving high impact on system availability while causing no impact to confidentiality or integrity.
