CVE-2026-108265 Privasys CVE debrief

Who should care

Defenders responsible for confidential applications inside Intel SGX enclaves, specifically those using enclave-os-mini, should assess exposure and prioritize verification and remediation efforts. This includes reviewing and updating affected systems and deployments, monitoring for potential exploitation attempts, and implementing compensating controls. Security teams and vulnerability management teams should also prioritize verification and remediation of

Why it matters

Defenders should care about CVE-2026-108265 because it allows an attacker to impersonate attested enclaves, potentially bypassing attestation mechanisms and elevating privileges in affected systems. The vulnerability requires verification of enclave-os-mini versions and upgrading to wasm-v0.40.0 or later to mitigate.

• Potential impersonation of attested enclaves
• Relay attacks on TLS connections
• Bypass of attestation mechanisms
• Elevation of privileges in affected systems

Technical summary

The SGX runtime's RA-TLS challenge certificate path did not bind the certificate public-key hash and client nonce to the active TLS session, allowing an attacker to relay a genuine quote onto another connection. This vulnerability affects enclave-os-mini and requires verification of enclave-os-mini versions and upgrading to wasm-v0.40.0 or later to mitigate. The vulnerability enables potential impersonation of attested enclaves and bypass of attestation mechanisms in affected systems. Defenders should prioritize verifying enclave-os-mini versions and upgrading to wasm-v0.40.0 or later to mitigate this vulnerability.

Defensive priority

Defenders should prioritize verifying enclave-os-mini versions and upgrading to wasm-v0.40.0 or later to mitigate this vulnerability.

Recommended defensive actions

• Verify enclave-os-mini versions and upgrade to wasm-v0.40.0 or later
• Review and update affected systems and deployments
• Monitor for potential exploitation attempts
• Perform vulnerability assessments
• Implement compensating controls
• Conduct asset inventory reviews
• Track changes and updates
