Descriptions

In the Linux kernel, the following vulnerability has been resolved:

serial: max310x: fix NULL pointer dereference in I2C instantiation

When trying to instantiate a max14830 device from userspace:

echo max14830 0x60 > /sys/bus/i2c/devices/i2c-2/new_device

we get the following error:

Unable to handle kernel NULL pointer dereference at virtual address...
...
Call trace:
max310x_i2c_probe+0x48/0x170 [max310x]
i2c_device_probe+0x150/0x2a0
...

Add check for validity of devtype to prevent the error, and abort probe
with a meaningful error message.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: serial: max310x: corrige la desreferencia del puntero NULL en la creación de instancias I2C Al intentar crear una instancia de un dispositivo max14830 desde el espacio de usuario: echo max14830 0x60 > /sys/bus/i2c/devices/i2c-2/ new_device obtenemos el siguiente error: No se puede manejar la desreferencia del puntero NULL del kernel en la dirección virtual... ... Rastreo de llamadas: max310x_i2c_probe+0x48/0x170 [max310x] i2c_device_probe+0x150/0x2a0... Agregar verificación de validez del tipo de desarrollo para evitar el error y cancelar la sonda con un mensaje de error significativo.
