Prior to version 0.9.0, the Java TLS ioctl probe reads user-controlled ioctl pointers with bpf_probe_read instead of bpf_probe_read_user. An instrumented local process can therefore point OBI at kernel memory and cause that memory to be copied into telemetry. 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:C/C:L/I:N/A:N","score":3.8},"cwes":["CWE-127","CWE-200"],"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-fjq3-ffvr-vm46","https://github.com/open-telemetry/opentelemetry-ebpf-instrumentation/security/advisories/GHSA-fjq3-ffvr-vm46"],"products":["opentelemetry:ebpf_instrumentation"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-45683","score":0.00174,"percentile":0.06905,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-fjq3-ffvr-vm46","url":"https://osv.dev/vulnerability/GHSA-fjq3-ffvr-vm46","summary":"OpenTelemetry eBPF Instrumentation: Java TLS ioctl kprobe allows kernel memory disclosure","modified":"2026-06-25T19:56:01.973430549Z","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-2026-5366","url":"https://osv.dev/vulnerability/GO-2026-5366","summary":"OpenTelemetry eBPF Instrumentation: Java TLS ioctl kprobe allows kernel memory disclosure in go.opentelemetry.io/obi","modified":"2026-06-25T19:45:34.237335633Z","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).
