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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-401","CWE-770"],"references":["https://github.com/open-telemetry/opentelemetry-ebpf-instrumentation/releases/tag/v0.9.0","https://github.com/open-telemetry/opentelemetry-ebpf-instrumentation/security/advisories/GHSA-962q-hwm5-52x5","https://github.com/open-telemetry/opentelemetry-ebpf-instrumentation/security/advisories/GHSA-962q-hwm5-52x5"],"products":["opentelemetry:ebpf_instrumentation"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-45682","score":0.00162,"percentile":0.05322,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-962q-hwm5-52x5","url":"https://osv.dev/vulnerability/GHSA-962q-hwm5-52x5","summary":"OpenTelemetry eBPF Instrumentation: CappedConcurrentHashMap leaks keys after removals","modified":"2026-06-25T19:56:08.892485568Z","packages":[{"ecosystem":"Go","name":"go.opentelemetry.io/obi","purl":"pkg:golang/go.opentelemetry.io/obi","ranges":["<0.9.0"],"fixed":["0.9.0"]}]},{"id":"GO-2026-5275","url":"https://osv.dev/vulnerability/GO-2026-5275","summary":"OpenTelemetry eBPF Instrumentation: CappedConcurrentHashMap leaks keys after removals in go.opentelemetry.io/obi","modified":"2026-06-25T19:45:23.215566904Z","packages":[{"ecosystem":"Go","name":"go.opentelemetry.io/obi","purl":"pkg:golang/go.opentelemetry.io/obi","ranges":["<0.9.0"],"fixed":["0.9.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
