{"schema":"threatline.record/2","record":{"id":"CVE-2026-108268","aliases":["GHSA-p5fp-g94g-g9m9"],"summary":"enclave-os-virtual: RA-TLS challenge certificates were not bound to the TLS session","details":"Enclave OS Virtual runs container workloads inside confidential virtual machines with end-to-end attestation. Prior to tdx-v0.2.43 and tdx-gpu-v0.6.27, the TDX/GPU RA-TLS certificate issuer placed the certificate public-key hash and client nonce in quote ReportData but omitted a value bound to the active TLS session. An attacker who obtained an enclave TLS private key could relay a genuine quote onto another connection, causing a relying party to accept an attacker-terminated connection as the attested enclave. This issue is fixed in tdx-v0.2.43 and tdx-gpu-v0.6.27.","categories":["Unclassified"],"product":"enclave-os-virtual","vendor":"Privasys","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-108268","source_modified_at":"2026-10-13T11:31:04.583Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"enclave-os-virtual","vendor":"Privasys","versions":[{"version":"< tdx-v0.2.43","status":"affected"},{"version":"< tdx-gpu-v0.6.27","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":9.1,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00128,"percentile":0.02231,"score_date":"2026-10-23"},"published_at":"2026-10-09T21:13:33.595Z","modified_at":"2026-10-13T11:31:04.583Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-108268","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T11:31:04.583Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-108268","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/Privasys/enclave-os-virtual/security/advisories/GHSA-p5fp-g94g-g9m9","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/Privasys/enclave-os-virtual/commit/9a6be91e29f2b6738d0b77c33cd1ad5cd3d8a347","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/Privasys/enclave-os-virtual/releases/tag/tdx-gpu-v0.6.27","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/Privasys/enclave-os-virtual/releases/tag/tdx-v0.2.43","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://privasys.org/blog/binding-attestation-to-the-tls-session","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-13T11:29:30.644389Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-13T11:31:04.583Z","content_hash":"3f9b072b34a974793b69b990201abc8f62a887619c3562092abac84f69cbb448"}}
