Title

hostapd和wpa_supplicant Total-Length字段长度拒绝服务漏洞

Description

hostapd是一个实现了无线接入点（AP）和认证服务器的守护进程。wpa_supplicant是一个运行在后台的守护进程，它主要用来支持WEP、WPA/WPA2和WAPI无线协议和加密认证。 hostapd和wpa_supplicant的EAP-pwd服务器端和peer端实现未能验证消息的长度是否大于Total-Length字段的长度，允许远程攻击者可提交特殊的消息使服务程序崩溃。

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
