Vulnerability from github – Published: 2025-10-21 21:54 – Updated: 2025-10-21 21:54

Summary

orx-pinned-vec has undefined behavior in index_of_ptr with empty slices

Details

The safe function index_of_ptr causes undefined behavior when called with an empty slice.

The issue occurs in the line ptr.add(slice.len() - 1) which underflows when slice.len() is 0, creating a pointer with a massive offset. According to Rust's safety rules, creating such a pointer causes immediate undefined behavior.

Severity

2.0 (Low)
