Vulnerability from github – Published: 2024-05-01 15:30 – Updated: 2025-09-18 15:30

Details

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

NTB: fix possible name leak in ntb_register_device()

If device_register() fails in ntb_register_device(), the device name allocated by dev_set_name() should be freed. As per the comment in device_register(), callers should use put_device() to give up the reference in the error path. So fix this by calling put_device() in the error path so that the name can be freed in kobject_cleanup().

As a result of this, put_device() in the error path of ntb_register_device() is removed and the actual error is returned.

As per the comment in\ndevice_register(), callers should use put_device() to give up the\nreference in the error path. So fix this by calling put_device() in the\nerror path so that the name can be freed in kobject_cleanup().\n\nAs a result of this, put_device() in the error path of\nntb_register_device() is removed and the actual error is returned.\n\n[mani: reworded commit message]"

Detection rules are retrieved from Rulezet.

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.
