5.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Namjae Jeon <linkinjeon@xxxxxxxxxx> commit b8fc56fbca7482c1e5c0e3351c6ae78982e25ada upstream. ksmbd_user_session_put should be called under smb3_preauth_hash_rsp(). It will avoid freeing session before calling smb3_preauth_hash_rsp().
