A symlink to `/` (e.g. `/tmp/rootlink -> /`) has a parent component, so it passes the check. GNU caches `/`'s dev/inode at startup and compares every traversed directory against it.\n\n**Impact:** `rm -rf --preserve-root` on a path that resolves through a symlink to `/` bypasses protection and can delete system directories. Recommendation: compare each entered directory's dev/inode against cached `/`.\n\n**Remediation:** Acknowledged by Canonical; fixed in commit 5e5968cd.\n\n---\n_Reported by Zellic in the *uutils coreutils Program Security Assessment* (prepared for Canonical, Jan 20 2026), audited commit `3a07ffc5a9bd4c283e75afa548ba1f1957bad242`.
