FKIE_CVE-2026-108265

Vulnerability from fkie_nvd - Published: 2026-10-09 21:17 - Updated: 2026-10-09 21:17
Severity
9.1 (Critical) - 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
Summary
Enclave OS Mini is a Rust-based runtime for confidential applications inside Intel SGX enclaves. Prior to wasm-v0.40.0, the SGX runtime's RA-TLS challenge certificate path 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 wasm-v0.40.0.
