Title

Linux BlueZ缓冲区溢出漏洞

Description

BlueZ是一套官方的Linux蓝牙协议栈。 Linux BlueZ 3.3-rc1及之后版本中存在缓冲区溢出漏洞，由于l2cap_parse_conf_rsp函数在解包之前未能正确检查rsp参数的长度，允许攻击者在内核堆栈中溢出64字节的缓冲区，并且无限制地制作数据以符合有效的L2CAP响应。

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.
