# PEAK-System PCAN driver: unvalidated object pointer dereference in type 0x4030 handling

PEAK-System's PCAN processing path for type 0x4030 uses a selected or returned object pointer without validating it before reading fixed fields during post-processing. The sources do not say what an attacker gains beyond a memory fault, so the impact is unknown.

_Summary, check and fix written by a model from the sources; labelled as such._
