The vulnerability is tied to permission handling, so once exploited, unauthorized users could gain confidential information. The impact is limited to confidentiality loss, with no evidence of code execution or denial of service.", "risk_and_exploitability": "The CVSS score of 6.3 indicates moderate severity, yet the EPSS value of less than 1% shows a very low probability of exploitation. The flaw is not present in the CISA Known Exploited Vulnerabilities catalog, suggesting limited current use. The likely attack scenario involves local privilege escalation on the device, exploiting the incorrect permission checks within the HDC module to read protected services. Remote exploitation is not documented."}}}}, "created": "2026-02-09T10:52:26.258689+00:00", "title": "Permission Control Flaw in HarmonyOS HDC Module Allows Confidentiality Impact", "updated": "2026-04-17T23:00:12.621287+00:00", "vendors": ["huawei", "huawei$PRODUCT$harmonyos"]}
