Descriptions
fs/nfs/nfs4client.c in the Linux kernel before 5.13.4 has incorrect connection-setup ordering, which allows operators of remote NFSv4 servers to cause a denial of service (hanging of mounts) by arranging for those servers to be unreachable during trunking detection.
El archivo fs/nfs/nfs4client.c en el kernel de Linux versiones anteriores a 5.13.4, presenta un ordenamiento incorrecto de la configuración de la conexión, que permite a operadores de servidores NFSv4 remotos causar una denegación de servicio (cuelgue de montajes) al disponer de que esos servidores sean inalcanzables durante la detección de trunking
