GHSA-GW7V-Q6J5-H9MV

Vulnerability from github – Published: 2025-09-18 15:30 – Updated: 2025-12-11 15:30

Details

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

USB: dwc3: fix memory leak with using debugfs_lookup()

When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfs_lookup_and_remove() instead which handles all of the logic at once.

Note, the root dentry for the debugfs directory for the device needs to be saved so we don't have to keep looking it up, which required a bit more refactoring to properly create and remove it when needed.

Severity

5.5 (Medium)

To make things simpler, just\ncall debugfs_lookup_and_remove() instead which handles all of the logic\nat once.\n\nNote, the root dentry for the debugfs directory for the device needs to\nbe saved so we don\u0027t have to keep looking it up, which required a bit\nmore refactoring to properly create and remove it when needed."

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.
