## Overview

### Summary
Logic bug in `decode_simple_table_slow` may cause integer arithmetic overflow when decoding Modular image with certain kind of MA tree, which may panic with `overflow-checks` enabled.

### Impact
Denial of service: any application passing untrusted JXL data to `JxlImage::render_frame` (or equivalent) can be
crashed. Affects all builds with overflow checks enabled, which includes debug builds and any release build
that sets `overflow-checks = true` in Cargo.toml or `[profile.*]`.

No memory corruption is possible — the panic fires before any unsafe code is reached.

## Affected packages

- `jxl-modular <= 0.11.2`

## Remediation

Upgrade to a patched release:

- `jxl-modular 0.11.3`
