Vulnerability from osv_openeuler – Published: 2023-10-13 11:06 – Updated: 2026-08-06 11:06 – Source website

Summary

openvswitch security update

Details

Open vSwitch is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license.

Security Fix(es):

A flaw was found in Open vSwitch that allows ICMPv6 Neighbor Advertisement packets between virtual machines to bypass OpenFlow rules. This issue may allow a local attacker to create specially crafted packets with a modified or spoofed target IP address field that can redirect ICMPv6 traffic to arbitrary IP addresses.(CVE-2023-5366)

Severity

7.1 (High)

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.
