CVE-2026-108268

CriticalCVSS 9.1
Published: Translated: NVD NIST

Summary

In versions prior to tdx-v0.2.43 and tdx-gpu-v0.6.27, Enclave OS Virtual 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.

Risk Assessment

Risk of accepting an unauthorized connection as a trusted enclave, potentially leading to security breaches and loss of trust in the system.

Recommendation

Update Enclave OS Virtual to version tdx-v0.2.43 or tdx-gpu-v0.6.27 (or later) to ensure the quote is bound to the active TLS session.

Original NVD description (English source)

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.
