CVE-2020-9203

Application interruption via crafted broadcast message

Published Jan 13, 2021 · Updated Aug 4, 2024

Resource-management error in Huawei P30 firmware allows local users to interrupt an application via a crafted broadcast message. An unspecified application sends the attacker-constructed broadcast while mishandling resources; Huawei does not identify the component or exact resource operation. The attacker must be able to log in to the smartphone, and the documented consequence is disruption of the customer use experience rather than data access or modification.
