HUAWEI P30 smartphones with versions earlier than 10.1.0.160(C00E160R2P11) have a denial of service vulnerability. A module does not deal with mal-crafted messages and it leads to memory leak. Attackers can exploit this vulnerability to make the device denial of service.Affected product versions include: HUAWEI P30 versions Versions earlier than 10.1.0.160(C00E160R2P11).

HUAWEI Mate 20 smartphones with versions earlier than 10.1.0.160(C00E160R2P11) have an improper authorization vulnerability. The software does not properly restrict certain operation in certain scenario, the attacker should do certain configuration before the user turns on student mode function. Successful exploit could allow the attacker to bypass the limit of student mode function. Affected product versions include: HUAWEI Mate 20 versions Versions earlier than 10.1.0.160(C00E160R3P8).

HUAWEI P30 smart phones with versions earlier than 10.1.0.160(C00E160R2P11) have an information exposure vulnerability. The system does not properly authenticate the application that access a specified interface. Attackers can trick users into installing malicious software to exploit this vulnerability and obtain some information about the device. Successful exploit may cause information disclosure.

HUAWEI P30 Pro smartphones with versions earlier than 10.1.0.123(C432E19R2P5patch02), versions earlier than 10.1.0.126(C10E11R5P1), and versions earlier than 10.1.0.160(C00E160R2P8) have a logic check error vulnerability. A logic error occurs when the software checking the size of certain parameter, the attacker should trick the user into installing a malicious application, successful exploit may cause code execution.

HUAWEI P30 Pro smartphones with versions earlier than 10.1.0.123(C432E19R2P5patch02), versions earlier than 10.1.0.126(C10E11R5P1), and versions earlier than 10.1.0.160(C00E160R2P8) have a buffer overflow vulnerability. The software access data past the end, or before the beginning, of the intended buffer when handling certain operations of certificate, the attacker should trick the user into installing a malicious application, successful exploit may cause code execution.

HUAWEI P30 smartphone with versions earlier than 10.1.0.135(C00E135R2P11) have an improper input verification vulnerability. An attribution in a module is not set correctly and some verification is lacked. Attackers with local access can exploit this vulnerability by injecting malicious fragment. This may lead to user information leak.

HUAWEI P30 and HUAWEI P30 Pro smartphones with versions earlier than 10.1.0.123(C432E22R2P5) and versions earlier than 10.1.0.160(C00E160R2P8) have an information disclosure vulnerability. Certain WI-FI function's default configuration in the system seems insecure, an attacker should craft a WI-FI hotspot to launch the attack. Successful exploit could cause information disclosure.

HUAWEI P30 with versions earlier than 10.1.0.160(C00E160R2P11) and HUAWEI P30 Pro with versions earlier than 10.1.0.160(C00E160R2P8) have an information disclosure vulnerability. Certain function's default configuration in the system seems insecure, an attacker should craft a WI-FI hotspot to launch the attack. Successful exploit could cause information disclosure.

HUAWEI P30 with versions earlier than 10.1.0.135(C00E135R2P11) have an improper signature verification vulnerability. The system does not improper check signature of specific software package, an attacker may exploit this vulnerability to load a crafted software package to the device.

HUAWEI P30 and HUAWEI P30 Pro with versions earlier than 10.1.0.135(C00E135R2P11) and versions earlier than 10.1.0.135(C00E135R2P8) have an insufficient integrity check vulnerability. The system does not check certain software package's integrity sufficiently. Successful exploit could allow an attacker to load a crafted software package to the device.
