CVE-2026-45682

OpenTelemetry eBPF Instrumentation: CappedConcurrentHashMap leaks keys after removals

Published Jun 2, 2026 CVSS 3.1 · 5.1 Medium EPSS < 1% KEV · Not listed
Description
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.
