CVE-2023-22301
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe kernel subsystem hmdfs within OpenHarmony-v3.1.5 and prior versions has an arbitrary memory accessing vulnerability which network attackers can launch a remote attack to obtain kernel memory data of the target system.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe hmdfs (HarmonyOS Distributed File System) kernel subsystem in OpenHarmony versions prior to v3.1.5 contains an arbitrary memory read vulnerability. Remote network attackers can exploit this flaw to read kernel memory contents, potentially exposing sensitive system data including credentials, keys, or other in-memory secrets.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine OpenHarmony versionCheck the system version through the device settings, system information command, or version file (typically accessible via 'getprop' or checking /etc/version on the device)Affected if Version is 3.1, 3.1.1, 3.1.2, 3.1.3, 3.1.4, or 3.1.5 (any version from 3.1 through 3.1.5 inclusive)
-
Confirm hmdfs subsystem presenceVerify that the hmdfs (HarmonyOS Distributed File System) kernel module or service is installed and running on the device; check for hmdfs-related processes, kernel modules, or system servicesAffected if hmdfs is present and active on the system (vulnerability exists in the hmdfs kernel subsystem)
-
Assess network exposureReview network configuration, listening services, and firewall rules to determine if the device is accessible from untrusted network segments; check for open network ports related to distributed file system functionalityAffected if Device has network accessibility from untrusted networks (remote attackers need network access to exploit this flaw)
User is affected if running OpenHarmony version 3.1 through 3.1.5 with hmdfs enabled and the device has network exposure to untrusted attackers.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade OpenHarmony to version 3.1.5 or later which contains the fix for this vulnerability. As a defensive measure, restrict network access to affected devices and implement network segmentation to limit exposure to remote attackers.
OpenHarmony 3.2.x or later (check official security advisories for exact fixed release)
- 1. Identify all OpenHarmony devices/systems running versions 3.1 through 3.1.5
- 2. Check OpenHarmony release notes or security advisories for CVE-2023-22301 fix information
- 3. If a patched version is available in the OpenHarmony 3.2.x or later release train, plan an upgrade path
- 4. Test the upgrade in a non-production environment first
- 5. Schedule maintenance window and apply the upgrade to production systems
- 6. Verify the hmdfs subsystem is functioning correctly after upgrade
- 7. Monitor for any anomalies and confirm the vulnerability is remediated
