{"cve":"CVE-2026-45686","nvd":{"published":"2026-06-02T16:16:43.493","modified":"2026-07-22T19:10:00.120","status":"Analyzed","description":"OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. From version 0.7.0 to before version 0.9.0, a remotely reachable integer overflow in OBI's memcached text protocol parser can crash the OBI process and cause denial of service. When parsing memcached storage commands such as set, add, replace, append, prepend, or cas, OBI accepts extremely large <bytes> values and adds the payload delimiter length without checking for overflow. A crafted request with <bytes> set to math.MaxInt or math.MaxInt-1 causes the computed payload length to wrap negative and triggers a runtime panic in LargeBufferReader.Peek. 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-190"],"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-43g7-cwr8-q3jh","https://github.com/open-telemetry/opentelemetry-ebpf-instrumentation/security/advisories/GHSA-43g7-cwr8-q3jh"],"products":["opentelemetry:ebpf_instrumentation"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-45686","score":0.00354,"percentile":0.29094,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-43g7-cwr8-q3jh","url":"https://osv.dev/vulnerability/GHSA-43g7-cwr8-q3jh","summary":"OpenTelemetry eBPF Instrumentation: Memcached payload length overflow can crash OBI","modified":"2026-06-25T18:56:17.639857256Z","packages":[{"ecosystem":"Go","name":"go.opentelemetry.io/obi","purl":"pkg:golang/go.opentelemetry.io/obi","ranges":[">=0.7.0 <0.9.0"],"fixed":["0.9.0"]}]},{"id":"GO-2026-5107","url":"https://osv.dev/vulnerability/GO-2026-5107","summary":"OpenTelemetry eBPF Instrumentation: Memcached payload length overflow can crash OBI in go.opentelemetry.io/obi","modified":"2026-06-25T18:45:20.876792287Z","packages":[{"ecosystem":"Go","name":"go.opentelemetry.io/obi","purl":"pkg:golang/go.opentelemetry.io/obi","ranges":[">=0.7.0 <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).
