  3. CVE-2025-47291
containerd is an open-source container runtime. A bug was found in the containerd's CRI implementation where containerd, starting in version 2.0.1 and prior to version 2.0.5, doesn't put usernamespaced containers under the Kubernetes' cgroup hierarchy, therefore some Kubernetes limits are not honored. This may cause a denial of service of the Kubernetes node. This bug has been fixed in containerd 2.0.5+ and 2.1.0+. Users should update to these versions to resolve the issue. As a workaround, disable usernamespaced pods in Kubernetes temporarily.

Summary
  • (es) containerd es un entorno de ejecución de contenedores de código abierto. Se detectó un error en la implementación de CRI de containerd: a partir de la versión 2.0.1 y anteriores a la 2.0.5, containerd no coloca los contenedores con espacio de nombre de usuario en la jerarquía de grupos de control de Kubernetes, por lo que no se respetan algunos límites de Kubernetes. Esto puede provocar una denegación de servicio del nodo de Kubernetes. Este error se ha corregido en containerd 2.0.5+ y 2.1.0+. Los usuarios deben actualizar a estas versiones para resolver el problema. Como workaround, deshabilite temporalmente los pods con espacio de nombre de usuario en Kubernetes.
