Source description

As published by the source; long descriptions are shortened.

The String API in iceoryx2-bb-container 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. The API methods `as_mut_bytes` and `deref_mut` where removed from the String API and their implementations (PolymorphicString, RelocatableString, and StaticString ) without replacement.

# Patch Next advisory brief: CVE-2026-92612

Advisory: Unsoundness in UTF-8 'String' trait
IDs: CVE-2026-92612, GHSA-8mq4-3mwq-qvg6
Record: https://patchnext.com/advisories/cve-2026-92612 (revision 1, source checked 23 Oct 2026, 22:04 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: iceoryx2-bb-container 0.10.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- crates.io iceoryx2-bb-container: affected >= 0.0.0-0, < 0.10.0; >= 0.11.0-0; fixed in 0.10.0

## Suggested inspection (read-only)
- crates.io iceoryx2-bb-container: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on iceoryx2-bb-container.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/RUSTSEC-2026-0294 (OSV record RUSTSEC-2026-0294 lists affected ranges: crates.io iceoryx2-bb-container >=0.0.0-0 =0.11.0-0)

Commands are suggestions: review each one before running it.
