CVE-2025-6969
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 · uneditedin OpenHarmony v5.1.0 and prior versions allow a local attacker cause DOS through improper input.
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 confidenceThis is a local denial-of-service vulnerability in OpenHarmony v5.1.0 and prior versions. A local attacker can cause the system or a component to become unavailable by providing improper input, likely triggering a crash, hang, or resource exhaustion due to missing or insufficient input validation.

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.
-
Identify OpenHarmony versionRun 'getprop ro.build.version.sdk' or check /system/etc/version.ini to determine the installed OpenHarmony versionAffected if Version is 5.0.3 or 5.1.0 (or any version prior to 5.1.0)
-
Determine if component input validation is in useReview application or system component logs in /var/log/ for error messages indicating input validation failures, crashes, or resource exhaustion related to user-provided dataAffected if Components handling external input are experiencing crashes, hangs, or unexpected termination
-
Verify local access controlsCheck user permissions and process isolation settings using 'ls -la /proc/' and review which local users have access to sensitive system componentsAffected if Untrusted local users have access to components that process input without proper validation
-
Monitor for denial-of-service symptomsReview system logs (dmesg, logcat) for repeated process crashes, hung tasks, or abnormal resource consumption patterns in affected componentsAffected if System or specific components are becoming unavailable, crashing repeatedly, or exhibiting resource exhaustion without other explanation
A user is affected if they are running OpenHarmony version 5.0.3 or 5.1.0 (or any version prior to 5.1.0) and experiencing unexplained component crashes, hangs, or service unavailability triggered by local input handling.

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.
From vendor dataUpgrade to a patched version of OpenHarmony beyond v5.1.0. If upgrading is not immediately feasible, restrict local access to trusted users only and monitor for service disruptions.
