CVE-2024-29971Public exploit

Enclave compromise via malicious signal injection

Published Jan 10, 2025 · Updated Jan 14, 2025

Signal-injection weakness in Scontain SCONE 5.8.0 and 5.9.0 allows attackers controlling the host OS to compromise SGX enclaves. SCONE forwards host signals into the enclave, allowing fake events to trigger benign program-defined handlers at arbitrary execution points and corrupt protected state. Control of the untrusted host operating system is required; successful exploitation exposes enclave secrets and violates application execution integrity.
