Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-191: Integer Underflow (Wrap or Wraparound), where the product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result. In Orx pinned vec, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
