CVE-2022-43495

Device reboot via malformed network-join message

Published Nov 3, 2022 · Updated Apr 30, 2025

Null pointer dereference in OpenHarmony 3.1.2 and earlier allows remote attackers to reboot devices via malformed network-join packets. EstablishAuthChannel in distributedhardware_device_manager accepts an abnormal join message and dereferences a null pointer instead of rejecting it. An unauthenticated attacker on an adjacent network can interrupt service by forcing the target device to reboot.
