CVE-2026-108265 | BDVDB-2026-385201 Detail
Privasysenclave-os-mini
Description#
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.
Impact#
Per CVSS v4.0: confidentiality impact high, integrity impact high, availability impact none. Attack vector: network.
