CVE-2026-92612 Eclipse Foundation CVE debrief

Who should care

Defenders of Rust applications using Eclipse iceoryx2 versions greater than v0.8.0, especially those processing untrusted input, should assess exposure and consider remediation. The vulnerability allows creation of invalid &str and triggering undefined behavior using entirely safe Rust. Defenders should verify if untrusted input is processed by affected versions to prevent potential undefined behavior. Remediation priority is low due to the low CVSS score,

Why it matters

CVE-2026-92612 is a low-severity vulnerability in Eclipse iceoryx2 that allows creation of invalid &str and triggering undefined behavior using entirely safe Rust. Defenders of Rust applications using affected versions should assess exposure and consider remediation.

• Verify if untrusted input is processed by affected versions to prevent potential undefined behavior
• Assess exposure in Rust applications using Eclipse iceoryx2 versions greater than v0.8.0
• Consider upgrading to v0.10.0 or later to apply the fix

Technical summary

The StaticString in Eclipse iceoryx2 versions greater than v0.8.0 exposes its contents as mutable bytes through safe APIs. When converted to a Rust string slice using String::as_str(), it does not validate UTF-8, allowing creation of invalid &str and triggering undefined behavior using entirely safe Rust. The vulnerability has a low CVSS score, but defenders should still assess exposure in Rust applications using affected versions, particularly those with untrusted input. The Eclipse iceoryx2 project has released a security advisory (GHSA-8mq4-3mwq-qvg6) and a fixed version (v0.10.0).

Defensive priority

Defenders should assess exposure in Rust applications using Eclipse iceoryx2 versions greater than v0.8.0, particularly those with untrusted input. Remediation priority is low due to the low CVSS score and lack of known exploitation.

Recommended defensive actions

• Assess exposure in Rust applications using Eclipse iceoryx2 versions greater than v0.8.0
• Verify if untrusted input is processed by affected versions
• Consider upgrading to v0.10.0 or later
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and NVD entry provide limited information about the vulnerability. The Eclipse iceoryx2 project has released a security advisory (GHSA-8mq4-3mwq-qvg6) and a fixed version (v0.10.0). The advisory confirms that the vulnerability allows creation of invalid &str and triggering undefined behavior using entirely safe Rust. Defenders should verify if untrusted input is processed by affected versions to prevent potential undefined behavior. The vulnerability has a low CVSS score, but defenders should still assess exposure in
