If `set_selinux_security_context` fails, cleanup uses `std::fs::remove_dir`, which cannot remove device nodes or FIFOs, leaving the mislabeled node behind.\n\n**Impact:** on SELinux-enforcing systems the node is created with the wrong context; the command reports failure but leaves a mislabeled device node that may bypass mandatory access control, and orphaned nodes can persist across reboots. Recommendation: use `setfscreatecon` before `mknod`, abort on failure, and use `remove_file` for cleanup.\n\n**Remediation:** Acknowledged by Canonical.\n\n---\n_Reported by Zellic in the *uutils coreutils Program Security Assessment* (prepared for Canonical, Jan 20 2026), audited commit `3a07ffc5a9bd4c283e75afa548ba1f1957bad242`.
