Vulnerability AssessmentAI
| Exploitation | Local access to a HarmonyOS device is required - AV:L confirms this is not remotely exploitable over a network. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD-assigned CVSS 3.1 base score is 4.0 (Medium) with vector AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local, unprivileged user on a HarmonyOS device crafts or obtains a malformed image file designed to trigger the out-of-bounds read in the image codec module. When the image is processed - for example, via a gallery app or messaging client rendering an attachment - the codec reads past the end of an allocated buffer, potentially leaking adjacent heap contents or crashing the decoding service. … |
| Remediation | The primary remediation is to apply the patches detailed in Huawei's July 2026 security bulletins. … Detailed patch versions, workarounds, and compensating controls in full report. |
