P30 smartphones with versions earlier than ELLE-AL00B 9.1.0.193(C00E190R1P21) have an out of bounds read vulnerability. The system does not properly validate certain length parameter which an application transports to kernel. An attacker tricks the user to install a malicious application, successful exploit could cause out of bounds read and information disclosure.

There is a man-in-the-middle (MITM) vulnerability on Huawei P30 smartphones versions before ELE-AL00 9.1.0.162(C01E160R1P12/C01E160R2P1), and P30 Pro versions before VOG-AL00 9.1.0.162 (C01E160R1P12/C01E160R2P1). When users establish connection and transfer data through Huawei Share, an attacker could sniff, spoof and do a series of operations to intrude the Huawei Share connection and launch a man-in-the-middle attack to obtain and tamper the data.
