An entry length near U32_MAX wraps it to a small\nvalue, bypasses the bounds check, and is then used to index the entry,\nreading far past the directory part -- an out-of-bounds read that oopses\nthe kernel.\n\nCompute the size as a u64 so it cannot truncate; the bounds check then\nrejects the entry. The trailer is supplied by the userspace client."
