CVE-2026-92612: CWE-749 in Eclipse Foundation Eclipse iceoryx™
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.
AI Analysis
Technical Summary
In Eclipse iceoryx™ versions >=0.8.1, the StaticString type exposes its contents as mutable bytes via safe APIs. The String::as_str() method then converts these bytes into a Rust &str without performing UTF-8 validation. This lack of validation allows an application to create an invalid &str, potentially causing undefined behavior despite using only safe Rust code. The vulnerability is identified as CWE-749 (Exposed Dangerous Method or Function).
Potential Impact
The vulnerability can cause undefined behavior in Rust applications that use the affected versions of Eclipse iceoryx™ by allowing invalid UTF-8 string slices to be created through safe APIs. The CVSS 4.0 base score is 1.0, indicating a low severity impact. There are no known exploits in the wild.
Mitigation Recommendations
No official patch or remediation information is provided. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should be cautious when using String::as_str() on StaticString contents and consider additional validation of UTF-8 encoding in their application logic.
