Comprehensive Technical Analysis of EUVD-2025-16071

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability identified as EUVD-2025-16071 affects the IEEE P802.11-REVme D1.1 through D7.0 standards, allowing for FragAttacks against mesh networks. This vulnerability enables an adversary to inject arbitrary frames into devices that support receiving non-SSP A-MSDU frames, particularly in networks using Wi-Fi Protected Access (WPA, WPA2, or WPA3) or Wired Equivalent Privacy (WEP). The issue arises from an incorrect fix for CVE-2020-24588.

Severity Evaluation: The CVSS (Common Vulnerability Scoring System) base score of 9.1 indicates a critical vulnerability. The scoring vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N highlights the following:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Unchanged (U)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): None (N)

This score underscores the high risk associated with this vulnerability, particularly due to its potential for significant confidentiality and integrity impacts.
