CVE-2024-51511

Local service interruption via unchecked parameter types

Published Nov 5, 2024 · Updated Nov 5, 2024

Improper input validation in Huawei HarmonyOS 5.0.0 allows local users to interrupt service through the WantAgent module. The module fails to verify parameter types before processing them, but Huawei has not disclosed the affected operation or interruption mode. Local reachability is required; the published impact is limited to availability, with no confidentiality or integrity impact.
