Description
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.
Affected configurations
• linux linux kernel (< 5.13.4)
• netapp hci bootstrap os
• netapp hci management node
• netapp solidfire
• netapp element software
• debian debian linux 9.0
• debian debian linux 11.0
