Title
openvswitch: use RCU protection in ovs_vport_cmd_fill_info()
Summary
In the Linux kernel, the following vulnerability has been resolved:
openvswitch: use RCU protection in ovs_vport_cmd_fill_info()
ovs_vport_cmd_fill_info() can be called without RTNL or RCU.
Use RCU protection and dev_net_rcu() to avoid potential UAF.

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.
