Enclave data disclosure via unaligned host reads
Published Dec 30, 2023 · Updated Nov 20, 2024
Information disclosure in SCONE Confidential Computing Platform before 5.8.0 allows local users to read protected enclave data. The __scone_dispatch function and other enclave entry functions fail to enforce eight-byte alignment for host-memory addresses and sizes, allowing stale CPU-buffer data to enter the enclave. Low-privileged access to an affected Intel SGX host is required; the demonstrated consequence is enclave-data disclosure without reported modification or service interruption.
