Details

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hci_conn: Fix memory leaks

When hci_cmd_sync_queue() failed in hci_le_terminate_big() or hci_le_big_terminate(), the memory pointed by variable d is not freed, which will cause memory leak. Add release process to error path.

Severity

5.5 (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.
