CVE-2022-37008Network attack vector

Service disruption via unverified recovery update package

Published Aug 9, 2022 · Updated Mar 6, 2026

Update verification bypass in Huawei HarmonyOS 2.0 and EMUI 11.0.0, 11.0.1, and 12.0.0 allows remote attackers to disrupt service. The recovery module accepts an update package for use without first verifying its authenticity, allowing invalid package data to enter the recovery path. No privileges or user interaction are required; published details establish a network path and high availability impact but do not specify whether exploitation causes a crash, hang, or reboot.
