Title
wifi: wil6210: debugfs: fix info leak in wil_write_file_wmi()
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: wil6210: debugfs: fix info leak in wil_write_file_wmi()
The simple_write_to_buffer() function will succeed if even a single
byte is initialized. However, we need to initialize the whole buffer
to prevent information leaks. Just use memdup_user().

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.
