CVE-2023-22301Network attack vector

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.
