Descriptions

A flaw was found in CRI-O that involves an experimental annotation leading to a container being unconfined. This may allow a pod to specify and get any amount of memory/cpu, circumventing the kubernetes scheduler and potentially resulting in a denial of service in the node.

Se encontró una falla en CRI-O que involucra una anotación experimental que lleva a que un contenedor no esté confinado. Esto puede permitir que un pod especifique y obtenga cualquier cantidad de memoria/CPU, eludiendo el programador de Kubernetes y potencialmente provocando una denegación de servicio en el nodo.
