RUSTSEC-2026-0133
Invalid pointer arithmetic in `iter()` and `iter_mut()`
The iter() and iter_mut() APIs compute
current = (&children[0] as *const *const RawAutoChild).sub(1), which
performs pointer subtraction going before the start of the allocation. This
is undefined behavior per Rust's pointer arithmetic rules.
This can be triggered through safe public APIs — iter() and iter_mut()
— with no unsafe required from the caller.
