Eclipse Openj9
Monthly
Remote unauthenticated attackers can crash Eclipse OpenJ9 JITServer instances (versions 0.21-0.58) by sending a specially crafted 32-byte TCP message, triggering a buffer over-read (CWE-125) that causes denial of service. The vulnerability requires no authentication or user interaction, affecting any exposed JITServer endpoint. CVSS 8.7 (High) reflects the severe availability impact, though EPSS data is not available for this recent CVE. Exploit code is publicly available via GitHub PR #23793, which demonstrates the bounds-checking fix, though no active exploitation is confirmed at time of analysis.
