kernel: Use-after-free in binder.c

A use-after-free in binder.c allows an elevation of privilege from an application to the Linux Kernel. No user interaction is required to exploit this vulnerability, however exploitation does require either the installation of a malicious local application or a separate vulnerability in a network facing application.Product: AndroidAndroid ID: A-141720095

The Bastet driver of Honor 9 Huawei smart phones with software of versions earlier than Stanford-AL10C00B175 has integer overflow vulnerability due to the lack of parameter validation. An attacker tricks a user into installing a malicious APP which has the root privilege; the APP can send a specific parameter to the driver of the smart phone, causing arbitrary code execution.

An attacker with the system privilege of a mobile can exploit this vulnerability to bypass the unlock code verification and unlock the mobile phone bootloader.

The Bastet driver of Honor 9 Huawei smart phones with software of versions earlier than Stanford-AL10C00B175 has a buffer overflow vulnerability due to the lack of parameter validation. An attacker tricks a user into installing a malicious APP which has the root privilege; the APP can send a specific parameter to the driver of the smart phone, causing arbitrary code execution

Honor 9X smartphones with versions earlier than 9.1.1.172(C00E170R8P1) have an improper authentication vulnerability. A logic error occurs when handling clock function, an attacker should do a series of crafted operations quickly before the phone is unlocked, successful exploit could allow the attacker to access clock information without unlock the phone.

There is an information disclosure vulnerability in certain Huawei smartphones (Mate 10;Mate 10 Pro;Honor V10;Changxiang 7S;P-smart;Changxiang 8 Plus;Y9 2018;Honor 9 Lite;Honor 9i;Mate 9). The software does not properly handle certain information of applications locked by applock in a rare condition. Successful exploit could cause information disclosure.

There is an improper authentication vulnerability in Huawei smartphones (Y9, Honor 8X, Honor 9 Lite, Honor 9i, Y6 Pro). The applock does not perform a sufficient authentication in a rare condition. Successful exploit could allow the attacker to use the application locked by applock in an instant.

There is a path traversal vulnerability in several Huawei smartphones. The system does not sufficiently validate certain pathnames from the application. An attacker could trick the user into installing, backing up and restoring a malicious application. Successful exploit could cause information disclosure.

There is an information leak vulnerability in some Huawei smartphones. An attacker may do some specific configuration in the smartphone and trick a user into inputting some sensitive information. Due to improper design, successful exploit may cause some information leak.
