CVE-2026-44108

Firewall bypass during shutdown

State: Published
Severity: 9.3 Critical
Published: Jul 30, 2026
Updated: Jul 30, 2026
Reserved: May 5, 2026

Description

Due to a flaw in the execution order of scripts during shutdown, the firewall is terminated prematurely during system shutdown. This creates a temporary window in which internal services may become externally accessible, potentially allowing an unauthenticated remote attacker to connect to these services, resulting in full system compromise.
