CRITICAL 9.8

DescriptionCVE.org

In the Eclipse OMR port library component since release 0.2.0, an API function to return the textual names of all supported processor features was not accounting for the separator inserted between processor features. If the output buffer supplied to this function was incorrectly sized, failing to account for the separator when determining when a write to the buffer was safe could lead to a buffer overflow. This issue is fixed in Eclipse OMR version 0.8.0.

Vulnerability AssessmentAI

Exploitation	Attacker must invoke Eclipse OMR port library's processor feature enumeration function (since 0.2.0, before 0.8.0) with deliberately undersized output buffer that omits separator byte accounting. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	CVSS 9.8. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	On specific hardware configurations, the buffer overflow in feature name enumeration corrupts adjacent memory, potentially enabling code execution.
Remediation	Update Eclipse OMR. Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Identify all systems and applications using Eclipse OMR and confirm affected versions. …
