In the Linux kernel, the following vulnerability has been resolved:
ksmbd: validate session id and tree id in compound request
smb2_get_msg() in smb2_get_ksmbd_tcon() and smb2_check_user_session()
will always return the first request smb2 header in a compound request.
if SMB2_TREE_CONNECT_HE is the first command in compound request, will
return 0, i.e. The tree id check is skipped.
This patch use ksmbd_req_buf_next() to get current command in compound.
