CVE-2024-58116
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 · uneditedBuffer overflow vulnerability in the SVG parsing module of the ArkUI framework Impact: Successful exploitation of this vulnerability may affect availability.
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 · high confidenceBuffer overflow vulnerability in the SVG parsing module of the ArkUI framework. The vulnerability occurs during SVG file processing where insufficient bounds checking allows a crafted SVG file to overflow a buffer, potentially causing a denial of service.

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 HarmonyOS versionCheck the system OS version by navigating to Settings > About Phone > Version on the HarmonyOS device, or run 'getprop ro.build.version.harmonyos' via ADB if availableAffected if The device is running HarmonyOS version 5.0.0 specifically
-
Confirm ArkUI framework presenceIdentify if the ArkUI framework is installed on the system by checking for ArkUI-related packages or libraries in the system partition, or review application dependencies that utilize ArkUI for UI renderingAffected if The ArkUI framework component is present on the system
-
Verify SVG parsing capability is in useCheck whether any applications on the device utilize SVG rendering or parsing functionality. This can be done by reviewing installed applications that handle graphical content, or by examining system logs for SVG-related processing activityAffected if SVG parsing or rendering functionality is actively used by any application on the device
-
Compare ArkUI component versionIf accessible, inspect the ArkUI framework component version to determine if it corresponds to the vulnerable build associated with HarmonyOS 5.0.0. This may require checking system app info or framework metadataAffected if The ArkUI framework version matches the build shipped with HarmonyOS 5.0.0 and has not been patched
A device is affected if it runs HarmonyOS 5.0.0 and has the ArkUI framework with SVG parsing capability enabled or in use.
