Given it worked for you in the installer, and that the file(1) command
is giving an "lhs/off overflow" error message, my suspicion would be
that either the file in question is corrupted or something else is
amiss with the disk it's on. Have you compared its size and integrity
with what's supplied in an install set?

Here's what I see for 10.1/amd64:

$ file iwlwifi-5000-2.ucode                                                                                  
iwlwifi-5000-2.ucode: data
$ ls -l iwlwifi-5000-2.ucode 
-r--r--r--  1 test  wheel  353240 Dec 16  2024 iwlwifi-5000-2.ucode
$ sha512 iwlwifi-5000-2.ucode 
SHA512 (iwlwifi-5000-2.ucode) = 3c8d3694f99909c13ff27610d1c362cb9c4c6d2db52471f700d00caf542e274ec89f9293481ac5323c6edb39b3440cc26845c1f5a40497b52e1376cb94b5d0f8
