Summary

In Eclipse iceoryx2 versions greater than v0.8.0, the StaticString exposes its contents as mutable bytes through safe APIs, while String::as_str() converts those bytes into a Rust string slice without validating UTF-8. An application can therefore create an invalid &str and trigger undefined behavior using entirely safe Rust.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of eclipse-iceoryx/iceoryx2 published their own advisory on GitHub. Reviewed sources take precedence over it.
