## Overview

In the Linux kernel, the following vulnerability has been resolved:

NFSD: Fix NFSv3 SETATTR/CREATE's handling of large file sizes

iattr::ia_size is a loff_t, so these NFSv3 procedures must be
careful to deal with incoming client size values that are larger
than s64_max without corrupting the value.

Silently capping the value results in storing a different value
than the client passed in which is unexpected behavior, so remove
the min_t() check in decode_sattr3().

Note that RFC 1813 permits only the WRITE procedure to return
NFS3ERR_FBIG. We believe that NFSv3 reference implementations
also return NFS3ERR_FBIG when ia_size is too large.

## Affected

- `linux_kernel < 5.4.295`
- `linux_kernel >= 5.5, < 5.10.220`
- `linux_kernel >= 5.11, < 5.15.24`
- `linux_kernel >= 5.16, < 5.16.10`
- `linux_kernel = 5.17`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.16.10`
