A stack overflow vulnerability exists in Huawei HarmonyOS's media platform. Successful exploitation may lead to service disruption, potentially causing application crashes or denial of service. This weakness arises from improper memory bounds handling and is classified as CWE‑121.

The vulnerability is known to affect devices running Huawei HarmonyOS, including consumer smartphones, laptops, vision devices, and wearables. No specific version information is provided, so all HarmonyOS releases that include the media platform are potentially vulnerable until a patch is issued.

The CVSS score of 2.8 indicates a moderate risk level, with the primary impact being availability. The EPSS score is not available, and the vulnerability is not listed in CISA KEV, suggesting limited public exploitation data. Exploitation likely requires local or privileged access to trigger the media platform, implying a low‑to‑moderate likelihood under typical attack scenarios. The lack of disclosed exploits reduces immediate concern, but the availability impact warrants swift remediation.
