Usage-limit bypass via incomplete Digital Balance restrictions
Published Aug 2, 2021 · Updated Aug 3, 2024
Incorrect authorization in Huawei smartphone Digital Balance allows physically proximate attackers to bypass enabled usage limits. When Digital Balance is enabled, its operation checks fail to enforce a restriction across a vendor-undisclosed sequence of actions. Physical possession of an affected phone is required; the bypass changes enforced limits, with no reported data disclosure or code execution.
