In the Linux kernel, the following vulnerability has been resolved: platform/x86: int3472: Check for adev == NULL Not all devices have an ACPI companion fwnode, so adev might be NULL. This can e.g. (theoretically) happen when a user manually binds one of the int3472 drivers to another i2c/platform device through sysfs. Add a check for adev not being set and return -ENODEV in that case to avoid a possible NULL pointer deref in skl_int3472_get_acpi_buffer().
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: platform/x86: int3472: Verificar si adev == NULL No todos los dispositivos tienen un fwnode complementario ACPI, por lo que adev podría ser NULL. Esto puede ocurrir (teóricamente) cuando un usuario vincula manualmente uno de los controladores int3472 a otro dispositivo i2c/platform a través de sysfs. Agregue una verificación para adev que no esté configurado y devuelva -ENODEV en ese caso para evitar una posible desreferencia de puntero NULL en skl_int3472_get_acpi_buffer().
