Title
scsi: bnx2fc: Make bnx2fc_recv_frame() mp safe
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: bnx2fc: Make bnx2fc_recv_frame() mp safe
Running tests with a debug kernel shows that bnx2fc_recv_frame() is
modifying the per_cpu lport stats counters in a non-mpsafe way. Just boot
a debug kernel and run the bnx2fc driver with the hardware enabled.

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.
