CVE-2025-22847
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 v5.0.2 and prior versions allow a local attacker cause DOS through out-of-bounds read.
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 confidenceOpenHarmony v5.0.2 and prior versions contain an out-of-bounds read vulnerability that allows a local attacker to read memory outside allocated buffers, leading to denial of service. The vulnerability stems from insufficient bounds checking in the affected code path, potentially allowing the attacker to trigger crashes or unexpected behavior.

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 the installed OpenHarmony versionRun the command 'getprop ro.build.version.sdk' or check /system/build.prop for the 'ro.build.version.sdk' property to determine the OpenHarmony version running on the deviceAffected if The version cannot be determined or is not visible through standard system properties
-
Compare version against affected rangeCheck if the installed OpenHarmony version falls within the range >= 4.1.0 and <= 5.0.2. Look for version information in system settings under 'About device' or use the command 'cat /proc/version' if availableAffected if The installed version is 4.1.0, 5.0.2, or any version in between these two releases
-
Verify the system is running OpenHarmonyConfirm the OS is OpenHarmony and not a derivative distribution. Check /etc/os-release or run 'cat /proc/version' to examine the kernel and system informationAffected if The system is confirmed to be running OpenHarmony and the version falls within the affected range
The environment is affected if OpenHarmony version 4.1.0 through 5.0.2 is installed, as these versions contain the out-of-bounds read vulnerability in an unspecified code path.

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 v5.0.2. If no upgrade is available, apply vendor-provided security patches addressing the out-of-bounds read vulnerability in the affected component.
