While the attack can be performed remotely and without authentication, it relies on sending specially crafted RDP packets that exploit a resource handling flaw, resulting in excessive consumption of system file descriptors and eventual denial of service. However, the vulnerability does not enable code execution, privilege escalation, or compromise of data integrity or confidentiality. The impact is therefore confined to service disruption rather than a direct security breach.\n\nAdditionally, the attack vector involves sustained resource abuse over time, requiring specific environmental conditions, such as systemd-managed user services with elevated file descriptor limits. This further limits the exploitability in default or hardened configurations. As such, the potential for widespread exploitation is constrained by the need for non-default service activation and prolonged interaction, reducing its overall security impact when compared to vulnerabilities that offer immediate compromise or broader applicability across system roles.",
