There are specific transporters to move malate into the bundle sheath cells.
These organic acids typically will not diffuse across the membrane. The
enzyme required for the decarboxylation is located in the bundle sheath
A good plant physiology text such as Taiz and Zeiger, Hopkins or Salisbury
and Ross should be able to provide additional information.

Can anyone help me with a question I recieved in my introdutory
class regardig c4 photosynthesis?
The student asked what keeps malate from being decarboxylated into
pyruvate in the mesophyll (what keeps it moving to the bundle sheath
this reaction rather than just happening in the meosphyll)
