DescriptionCVE.org

Permission control vulnerability in the file system. Impact: Successful exploitation of this vulnerability may affect service confidentiality.

AnalysisAI

Local information disclosure in Huawei HarmonyOS and EMUI stems from a flawed permission-control check in the file system, letting a local actor read data that should be access-restricted. Exploitation requires local access plus user interaction (CVSS UI:R), and Huawei's own scoring rates it high impact; no public exploit was identified at time of analysis and it is not listed in CISA KEV. Note the vendor CVSS also asserts integrity and availability impact, which the one-line description (confidentiality only) does not substantiate.
