Permission control vulnerability in the event notification module.Impact: Successful exploitation of this vulnerability may affect availability.
AnalysisAI
HarmonyOS 6.1.0's event notification module contains a permission control flaw (CWE-275) that allows a locally-executing process without elevated privileges to disrupt the availability of the notification service. Both the CVSS vector (C:N/I:N/A:H) and Huawei's own bulletin text confirm the impact is strictly an availability denial - confidentiality and integrity are unaffected. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires code execution on the target HarmonyOS 6.1.0 device; the attack vector is strictly local (AV:L) with no remote exploitation path indicated. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.2 (Medium) score accurately reflects the constrained impact profile: AV:L limits exploitation to code already running on the target device, and the sole impact is availability (A:H). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the Huawei September 2026 security update for the relevant device category: consumer devices at https://consumer.huawei.com/en/support/bulletin/2026/9/, Vision smart displays at https://consumer.huawei.com/en/support/bulletinvision/2026/9/, wearables at https://consumer.huawei.com/en/support/bulletinwearables/2026/9/, and laptops at https://consumer.huawei.com/en/support/bulletinlaptops/2026/9/. … Detailed patch versions, workarounds, and compensating controls in full report. |
