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
| CPE | Name | Operator | Version |
|---|---|---|---|
| linux:linux_kernel | linux linux kernel | lt | 5.13.4 |
