Executive Summary

[{'type': 'paragraph', 'content': 'CVE-2026-3271 is a critical buffer overflow vulnerability found in the Tenda F453 router, version 1.0.0.3. It exists in the function fromP2pListFilter within the httpd component, specifically in the file /goform/P2pListFilterof. The vulnerability arises due to improper handling of the "page" argument, where input data is copied without verifying that the input size fits the destination buffer, leading to a buffer overflow condition.'}, {'type': 'paragraph', 'content': 'This flaw allows remote attackers to exploit the buffer overflow remotely without authentication, potentially enabling arbitrary code execution or denial of service.'}] [2, 3]
