CVE-2026-45682 Details
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.
A memory leak vulnerability has been identified in OpenTelemetry eBPF Instrumentation versions prior to 0.9.0. The issue arises from a custom CappedConcurrentHashMap used for tracking Java TLS state, which fails to remove keys from its insertion-order queue when entries are deleted. In long-running instrumented JVMs, this can lead to unbounded queue growth and heap memory exhaustion, particularly during periods of frequent TLS connection churn.
Users can upgrade to OpenTelemetry eBPF Instrumentation version 0.9.0 or later, where this vulnerability has been patched.
