How could an attacker exploit this vulnerability?
An attacker could exploit this vulnerability by sending specially crafted network responses to a system running the Windows Print Spooler service.

The issue requires the attacker to already have low‑privilege authentication to the target environment, and there is no indication in the provided information that user interaction is required.
