CVE-2026-45682: Opentelemetry Ebpf Instrumentation

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, the custom CappedConcurrentHashMap introduced for Java TLS state tracking never removes keys from its insertion-order queue when entries are deleted. In long-running instrumented JVMs, repeated connection churn can therefore grow the queue without bound and exhaust heap memory. This issue has been patched in version 0.9.0.

Affected products

• Opentelemetry Ebpf Instrumentation: before 0.9.0 (fixed in 0.9.0)
