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.","state":0,"publishedAt":"2026-10-09T21:13:33.595+00:00","modifiedAt":"2026-10-13T11:31:04.583+00:00","affected":[{"ecosystem":"Vendor product","name":"enclave-os-virtual","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Privasys\",\n                    \"product\": \"enclave-os-virtual\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< tdx-v0.2.43\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"< tdx-gpu-v0.6.27\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":9.1,"severity":"CRITICAL"}],"references":["https://github.com/Privasys/enclave-os-virtual/security/advisories/GHSA-p5fp-g94g-g9m9","https://github.com/Privasys/enclave-os-virtual/commit/9a6be91e29f2b6738d0b77c33cd1ad5cd3d8a347","https://github.com/Privasys/enclave-os-virtual/releases/tag/tdx-gpu-v0.6.27","https://github.com/Privasys/enclave-os-virtual/releases/tag/tdx-v0.2.43","https://privasys.org/blog/binding-attestation-to-the-tls-session"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-108268","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-108268","identifiers":["CVE-2026-108268"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
