"value": "An issue was discovered in the Linux kernel 4.18 through 5.6.11 when unprivileged user namespaces are allowed. A user can create their own PID namespace, and mount a FUSE filesystem. Upon interaction with this FUSE filesystem, if the userspace component is terminated via a kill of the PID namespace's pid 1, it will result in a hung task, and resources being permanently locked up until system reboot. This can result in resource exhaustion."

Un usuario puede crear su propio espacio de nombre PID, y montar un sistema de archivos FUSE. Tras interactuar con este sistema de archivos FUSE, si el componente namespace es finalizado por medio de la eliminaci\u00f3n del pid 1 del espacio de nombre PID, resultar\u00e1 en una suspensi\u00f3n de tarea, y los recursos se bloquear\u00e1n permanentemente hasta que se reinicie el sistema. Esto puede resultar en un agotamiento de los recursos."
