Statement
Red Hat has evaluated this vulnerability as having a Low severity impact because triggering the condition requires CPU hotplug operations on hardware platforms supporting extended feature disable (XFD). Unprivileged local users cannot perform CPU hotplug actions, requiring privileged access or specific hypervisor-level interventions to initiate the event that leads to kernel instability. As a result, the risk of unprivileged denial-of-service in typical enterprise environments remains minimal.
