Title
be2net: pass wrb_params in case of OS2BMC
Summary
In the Linux kernel, the following vulnerability has been resolved:
be2net: pass wrb_params in case of OS2BMC
be_insert_vlan_in_pkt() is called with the wrb_params argument being NULL
at be_send_pkt_to_bmc() call site. This may lead to dereferencing a NULL
pointer when processing a workaround for specific packet, as commit
bc0c3405abbb ("be2net: fix a Tx stall bug caused by a specific ipv6
packet") states.
The correct way would be to pass the wrb_params from be_xmit().
Severity
No CVSS data available.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

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.
