This vulnerability (CVE-2026-34862) affects Huawei HarmonyOS 6.0.0 and arises from a race condition in the power consumption statistics module due to improper synchronization of shared resources (CWE-362). The flaw could be triggered by a privileged local attacker to affect system availability. The CVSS vector (AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:H/A:H) indicates local attack vector, low attack complexity, high privileges required, no user interaction, unchanged scope, low confidentiality impact, high integrity impact, and high availability impact. No patch or vendor remediation information is currently provided.

Successful exploitation may lead to availability issues in the affected HarmonyOS system, potentially disrupting normal operation. The integrity impact is also rated high, which may indicate possible unauthorized modification of data related to power consumption statistics. Confidentiality impact is low. The vulnerability requires local access with high privileges to exploit.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to privileged accounts and monitor for unusual behavior related to power consumption statistics. No official mitigation or workaround has been provided by Huawei at this time.
