08 Aug 2021 — 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 (c... • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.13.4 •
