Secret-data disclosure via insufficiently filtered RAPL readings
Published Sep 16, 2024 · Updated Nov 3, 2025
Observable discrepancy in the Intel Processor RAPL interface allows privileged local users to infer secret data through energy measurements. MSR_PKG_ENERGY_TIME_STATUS exposes package energy readings without sufficient filtering, preserving correlations between processed data and measured consumption. High privileges and local access are required; repeated power analysis can recover secrets such as cryptographic keys across trust boundaries, including from SGX enclaves.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
