CVE-2018-3615: Systems with microprocessors utilizing speculative execution and Intel software guard extensions (Intel SGX...

Systems with microprocessors utilizing speculative execution and Intel software guard extensions (Intel SGX) may allow unauthorized disclosure of information residing in the L1 data cache from an enclave to an attacker with local user access via a side-channel analysis.

Security readout for executives and security teams

This issue can let a local, low-privileged user read sensitive information that Intel SGX enclaves were meant to protect. It is not described as remotely exploitable in the supplied sources, but it undermines a hardware trust boundary used for secrets and high-assurance workloads. Exposure is most likely on Intel-based systems where SGX is enabled or where applications depend on SGX enclave confidentiality. Multi-user hosts, shared compute, developer workstations, and servers running enclave-backed workloads deserve priority review. Treat as high priority for environments relying on SGX to protect secrets. Broader enterprise urgency depends on whether local untrusted users or shared workloads exist on affected Intel systems. Mitigation focus: Review Intel SA-00161 and applicable vendor advisories for affected platforms.; Apply vendor-approved BIOS, firmware, microcode, and operating system updates where available.; Prioritize systems using SGX or handling enclave-protected secrets..
