Title
net: ethernet: nixge: fix NULL dereference
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: nixge: fix NULL dereference
In function nixge_hw_dma_bd_release() dereference of NULL pointer
priv->rx_bd_v is possible for the case of its allocation failure in
nixge_hw_dma_bd_init().
Move for() loop with priv->rx_bd_v dereference under the check for
its validity.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

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.
