A flaw was found in systemd, a core component of Linux operating systems. A local user, without special privileges, can exploit this vulnerability. By manipulating a specific systemd unit configuration where delegation is enabled and the user is not set, the user can trigger an internal error, leading to a Denial of Service (DoS). This means the affected system may become unresponsive or crash, impacting its availability.
