CVE-2026-75131

Description

A flaw was found in NetworkManager-l2tp. This privilege escalation vulnerability allows local users, who have permissions to create VPN connections, to execute arbitrary code as root. This is achieved by injecting options into the pppd (Point-to-Point Protocol Daemon) through a specially crafted VPN username. An attacker can embed a double-quote character or whitespace in the username to bypass quoting in the pppd options file, enabling the pppd process to load an attacker-controlled shared object.
