Out-of-bounds read vulnerability in the image codec module. Impact: Successful exploitation of this vulnerability may affect service confidentiality.
AnalysisAI
Out-of-bounds read in HarmonyOS's image codec module exposes limited memory content and may cause service instability, affecting confidentiality and availability at a low severity level. The flaw resides in image processing logic and is reachable by a local, unprivileged actor who can trigger image decoding - such as by supplying a crafted image file. …

Vulnerability AssessmentAI
| Exploitation | Local access to the HarmonyOS device is required - this vulnerability cannot be triggered remotely. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 5.1 with vector AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L positions this as a medium-severity, locally-exploitable issue. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local attacker or malicious application on the HarmonyOS device supplies a specially crafted image file to the image codec module - either directly via a locally-installed app or by placing the file in a directory that triggers automatic processing (e.g., gallery indexing). The codec reads beyond the allocated buffer boundary, leaking a small amount of adjacent memory that may contain sensitive data, or causing the image service to crash. … |
| Remediation | Users and administrators should consult the Huawei July 2026 security bulletins for their respective device class and apply available over-the-air (OTA) or manual firmware updates: consumer devices at https://consumer.huawei.com/en/support/bulletin/2026/7/, Vision devices at https://consumer.huawei.com/en/support/bulletinvision/2026/7/, wearables at https://consumer.huawei.com/en/support/bulletinwearables/2026/7/, and laptops at https://consumer.huawei.com/en/support/bulletinlaptops/2026/7/. … Detailed patch versions, workarounds, and compensating controls in full report. |
