Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: amd_sfh: Fix memory leak in amd_sfh_work
Kmemleak tool detected a memory leak in the amd_sfh driver.
====================

====================
The fix is to freeing request_list entry once the processed entry is
removed from the request_list.

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.
