Descriptions

A flaw was found in cri-o, as a result of all pod-related processes being placed in the same memory cgroup. This can result in container management (conmon) processes being killed if a workload process triggers an out-of-memory (OOM) condition for the cgroup. An attacker could abuse this flaw to get host network access on an cri-o host.

Se encontró un fallo en cri-o, como un resultado de que todos los procesos relacionados con pod están colocados en el mismo grupo de memoria. Esto puede resultar en que se eliminen los procesos de administración de contenedores (conmon) si un proceso de carga de trabajo desencadena una condición de falta de memoria (OOM) para el cgroup. Un atacante podría abusar de este fallo para conseguir acceso a la red del host en un host de cri-o.
