Kernel memory disclosure via HMDFS out-of-bounds read
Published Mar 10, 2023 · Updated Feb 27, 2025
Out-of-bounds read in OpenHarmony's HMDFS kernel subsystem 3.1 through 3.1.5 allows remote authenticated users to read kernel memory. The vendor describes the faulty operation only as an HMDFS out-of-bounds memory read and does not identify the function or network input path. Exploitation requires high privileges without user interaction; the published impact is limited to disclosure of target kernel memory data.

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.
