NULL pointer dereference vulnerability exists in Defense Platform Home Edition Ver.3.9.51.x and earlier. If an attacker provides specially crafted data to the specific process of the Windows system where the product is running, the system may cause a Blue Screen of Death (BSOD), and as a result, cause a denial-of-service (DoS) condition.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
