CVE-2026-78424Network attack vectorHinoki check available

Authenticated command execution via crafted sniffer filter

Published Sep 28, 2026 · Updated Sep 28, 2026

OS command injection in SUSE NeuVector 5.6.0 through 5.6.1 lets remote authenticated users execute commands via packet-capture filters. Improper handling of a crafted sniffer filter allows command syntax to reach the privileged enforcer container. Access requires namespaced Runtime Policies write permission or NeuVector's internal gRPC certificate key pair; execution can compromise the worker node.
