Uncontrolled memory allocation in Huawei's vibration service crashes affected HarmonyOS and EMUI devices, resulting in a denial-of-service condition impacting device availability. The flaw is remotely triggerable with no privileges required but demands user interaction, consistent with delivery via crafted content such as a malicious application, webpage, or message that exercises the vibration API. No public exploit code or active exploitation has been identified at time of analysis, though Huawei has issued a July 2026 security bulletin addressing the issue.
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.
Permission control failure in the Bluetooth module of Huawei HarmonyOS and EMUI exposes devices to local exploitation that can degrade Bluetooth service availability and leak limited data. The flaw, classified under CWE-264, allows a local process operating without elevated privileges to bypass Bluetooth permission enforcement, potentially disrupting connectivity or reading restricted information. No public exploit or CISA KEV listing exists at time of analysis, but Huawei has disclosed this via its July 2026 security bulletin.
