Information disclosure via out-of-bounds firmware read
Published Jun 9, 2021 · Updated Aug 4, 2024
An out-of-bounds read in Intel Converged Security and Manageability Engine allows local users to disclose data through privileged access. An unnamed firmware subsystem reads beyond a buffer boundary and exposes adjacent data, but Intel has not disclosed the subsystem, input path, or affected data. Exploitation requires high privileges and local access to a system containing affected CSME firmware; the published impact excludes integrity and availability loss.

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.
- Affected versionversion=versions before 12.0.81, 13.0.47, 13.30.17, 14.1.53 and 14.5.32
