NVIDIA GPU Display Driver for Windows contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for private IOCTLs, where an attacker with local unprivileged system access may cause a NULL pointer dereference, which may lead to denial of service in a component beyond the vulnerable component.

Weakness

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.
