Its documented impact is denial of service only (crashing the ash process) with no confidentiality or integrity effect, so it does not endanger system-wide services. If BusyBox ash is not exposed as an interactive login shell and exists only in non-interactive components (such as initramfs or minimal containers), untrusted users have no practical path to trigger evalcommand(), making this safe to deprioritize.",
