Descriptions

The memory resource controller (aka memcg) in the Linux kernel allows local users to cause a denial of service (deadlock) by spawning new processes within a memory-constrained cgroup.

El controlador de recursos de memoria (también conocido como memcg) en el kernel de Linux permite que usuarios locales provoquen una denegación de servicio (deadlock) generando nuevos procesos en un cgroup con límite de memoria.

It was found that the Linux kernel memory resource controller's (memcg) handling of OOM (out of memory) conditions could lead to deadlocks. An attacker able to continuously spawn new processes within a single memory-constrained cgroup during an OOM event could use this flaw to lock up the system.
