Title

QEMU AMD PC-Net II Ethernet Controller CRC Handling缓冲区溢出漏洞

Description

QEMU是法国程序员法布里斯-贝拉（Fabrice Bellard）所研发的一套模拟处理器软件。该软件具有速度快、跨平台等特点。 QEMU的hw/net/pcnet.c文件中的‘pcnet_transmit’函数中存在缓冲区溢出漏洞，该漏洞源于程序使用loopback模式接收数据包时，未能正确验证接收数据的大小。攻击者可利用该漏洞造成拒绝服务（QEMU实例崩溃），或执行任意代码。

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.
