Title
nvme-fc: Prevent null pointer dereference in nvme_fc_io_getuuid()
Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-fc: Prevent null pointer dereference in nvme_fc_io_getuuid()
The nvme_fc_fcp_op structure describing an AEN operation is initialized with a
null request structure pointer. An FC LLDD may make a call to
nvme_fc_io_getuuid passing a pointer to an nvmefc_fcp_req for an AEN operation.
Add validation of the request structure pointer before dereference.

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.
