CVE-2025-54617
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 · uneditedStack-based buffer overflow vulnerability in the dms_fwk module. Impact: Successful exploitation of this vulnerability can cause RCE.
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 confidenceA stack-based buffer overflow vulnerability exists in the dms_fwk module. By overflowing a stack-allocated buffer, an attacker can overwrite return addresses or adjacent memory, potentially achieving remote code execution with the privileges of the affected process.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.
Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 HarmonyOS versionCheck the system version on the device. On HarmonyOS, you can typically find this in Settings > About Device, or by running 'getprop ro.build.version.release' or 'sysprop ro.build.version.sdk' via ADB or terminal.Affected if The installed version is exactly 5.1.0
-
Verify the dms_fwk module is presentCheck if the dms_fwk module exists on the system. This can typically be found in /system/lib/ or /system/lib64/ directories, or listed in the system module manifest. Use 'ls -la /system/lib*/libdms_fwk*' or similar commands accessible via ADB or root access.Affected if The dms_fwk module is present on the device
-
Confirm the module is actively loaded or in useInspect if the dms_fwk module is currently loaded or actively referenced by running processes. Use commands like 'ps -A | grep dms' or check /proc/*/maps for references to the module if you have access.Affected if The dms_fwk module is loaded into memory and running as part of an active process
-
Review system logs for crash indicatorsCheck system logs (logcat on Android-based HarmonyOS, or /var/log/ directories) for any crashes, segfaults, or abnormal terminations involving the dms_fwk process, particularly those mentioning stack overflow, buffer overflow, or memory corruption.Affected if There are recent crash logs or error messages involving dms_fwk that suggest exploitation attempts or successful overflows
A system is affected only if it runs Huawei HarmonyOS version exactly 5.1.0 AND has the dms_fwk module present and actively loaded.

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 dataApply available patches or updates for the dms_fwk module. If no patch exists, conduct code review of the vulnerable module to identify and remediate unsafe buffer operations (e.g., unbounded strcpy, sprintf, or similar functions). Implement input validation and consider deploying runtime exploit mitigation protections.
