Data disclosure via Bluetooth out-of-bounds read
Published Feb 9, 2023 · Updated Mar 24, 2025
Out-of-bounds read in Huawei HarmonyOS and EMUI allows physically proximate attackers to disclose data through Bluetooth input. Public vendor material identifies an out-of-memory condition in the Bluetooth module but does not disclose the specific routine, message type, or bounds error that reads beyond the intended buffer. Exploitation requires Bluetooth proximity and no authentication or user interaction; reported impact is limited to confidentiality, with no integrity or availability impact.
