{"id":"CVE-2026-108268","published":"2026-10-09T22:16:59.643","lastModified":"2026-10-13T12:17:12.633","description":"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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-346"],"vendors":[],"products":[],"references":[{"url":"https://github.com/Privasys/enclave-os-virtual/commit/9a6be91e29f2b6738d0b77c33cd1ad5cd3d8a347","tags":[]},{"url":"https://github.com/Privasys/enclave-os-virtual/releases/tag/tdx-gpu-v0.6.27","tags":[]},{"url":"https://github.com/Privasys/enclave-os-virtual/releases/tag/tdx-v0.2.43","tags":[]},{"url":"https://github.com/Privasys/enclave-os-virtual/security/advisories/GHSA-p5fp-g94g-g9m9","tags":[]},{"url":"https://privasys.org/blog/binding-attestation-to-the-tls-session","tags":[]}],"exploitRefs":[{"url":"https://github.com/Privasys/enclave-os-virtual/commit/9a6be91e29f2b6738d0b77c33cd1ad5cd3d8a347","tags":[]},{"url":"https://github.com/Privasys/enclave-os-virtual/releases/tag/tdx-gpu-v0.6.27","tags":[]},{"url":"https://github.com/Privasys/enclave-os-virtual/releases/tag/tdx-v0.2.43","tags":[]},{"url":"https://github.com/Privasys/enclave-os-virtual/security/advisories/GHSA-p5fp-g94g-g9m9","tags":[]}],"hasPoc":true,"ai":null}
