Using Powershell to update AD Users staring from a CSV

Question

Hi!
i need to update a list of AD Users and change for all of them the same attribute with the same value.
i have a csv containing just the list of users cn, ho can i make the query on this attribute?
I start to build the command and i've something like that:
$USERS = Import-CSV C:\Users\Users2.csv
$USERS | Foreach{Get-ADUser
-filter {cn -eq $_.name} |
Set-ADUser -replace @{info=""}
but i got the following error for every entry in the csv:
Get-ADUser : Property: 'name' not found in object of type:
'System.Management.Automation.PSCustomObject'.
At line:1 char:18
+ $USERS | Foreach{Get-ADUser -filter {cn -eq $_.name}}
+                  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [Get-ADUser], ArgumentExcep
   tion
    + FullyQualifiedErrorId : ActiveDirectoryCmdlet:System.ArgumentException,M
   icrosoft.ActiveDirectory.Management.Commands.GetADUser
something wrong for the filter in the command, someone can help?
Thanks!

Added Write-Verbose to help troubleshoot the data being sent to Get-ADUser to make sure that Name actually has data with it.
Also, the AD module sometimes behaves a little odd when using $_. with the Filter. I've found it better to declare a variable name prior to sending it to the filter like this:
$USERS = Import-CSV C:\Users\Users2.csv
$USERS | Foreach{
Write-Verbose "Name: $($_)" -Verbose
$Name = $_.Name
Get-ADUser -filter {cn -eq $Name} | Set-ADUser -replace @{info=""}
