Buffer Overflow Vulnerability in Eclipse OMR Port Library

CVE-2026-1188

What is CVE-2026-1188?

In the Eclipse OMR port library component, an API function responsible for returning textual names of supported processor features had a vulnerability due to incorrect handling of output buffer sizes. Specifically, the function did not properly account for separators between features, which could lead to a buffer overflow when a malicious actor inputs values that exceed the allocated buffer size. This flaw was addressed in Eclipse OMR version 0.8.0, enforcing better checks to prevent buffer overflows and ensuring system integrity.
