CVE-2021-41229 (GCVE-0-2021-41229)

Vulnerability from cvelistv5 – Published: 2021-11-12 00:00 – Updated: 2025-11-04 16:09

Title

Memory leak in BlueZ

Summary

BlueZ is a Bluetooth protocol stack for Linux. In affected versions a vulnerability exists in sdp_cstate_alloc_buf which allocates memory which will always be hung in the singly linked list of cstates and will not be freed. This will cause a memory leak over time. The data can be a very large object, which can be caused by an attacker continuously sending sdp packets and this may cause the service of the target device to crash.

Severity

4.3 (Medium)

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.
