Prior to version 0.9.0, OBI replays BPF probe hits into histogram observations by looping once per recorded run count. On busy systems, the run-count delta can become very large, causing the metrics exporter to spend excessive CPU time in a tight loop every collection interval. This issue has been patched in version 0.9.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-400","CWE-834"],"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-89c6-vpcj-7vj4","https://github.com/open-telemetry/opentelemetry-ebpf-instrumentation/security/advisories/GHSA-89c6-vpcj-7vj4"],"products":["opentelemetry:ebpf_instrumentation"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-45680","score":0.00319,"percentile":0.24895,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-89c6-vpcj-7vj4","url":"https://osv.dev/vulnerability/GHSA-89c6-vpcj-7vj4","summary":"OpenTelemetry eBPF Instrumentation: Unbounded BPF internal metrics replay can exhaust CPU","modified":"2026-06-25T19:56:11.982408926Z","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-2026-5248","url":"https://osv.dev/vulnerability/GO-2026-5248","summary":"OpenTelemetry eBPF Instrumentation: Unbounded BPF internal metrics replay can exhaust CPU in go.opentelemetry.io/obi","modified":"2026-06-25T19:45:21.746388649Z","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).
