Please follow the article to configure the user profile service.

Once the user profile is configured check the mange user properties, this will be populated latest information from AD.
Once this is done then it will automatically update the user information in the "User Information List".
if it does not update the user information you can use the below power shell command to update the same.
$web = (Get-SPSite http://site).rootweb
$web | Set-SPUser -Identity "user details" -SyncFromAD.
Hope this helps you to resolve the issue.
