CVE-2026-45682 | BDVDB-2026-337353 Detail

open-telemetryopentelemetry-ebpf-instrumentation

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.

Impact#

Per CVSS v3.1: confidentiality impact none, integrity impact none, availability impact high. Attack vector: local.

Weaknesses#

CWE-401 Missing Release of Memory after Effective Lifetime
CWE-770 Allocation of Resources Without Limits or Throttling
