Local information disclosure via incomplete prediction barrier
Published Mar 14, 2024 · Updated Feb 13, 2025
Information disclosure in Intel Processors' return prediction allows local users to read sensitive data across execution contexts. An incomplete branch prediction barrier permits return predictor targets to remain non-transparently shared between contexts. Low-privilege local execution is required; the documented consequence is confidentiality loss without integrity or availability impact.

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.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
