Descriptions

In the Linux kernel, the following vulnerability has been resolved: i3c: master: mipi-i3c-hci: Fix a kernel panic for accessing DAT_data. The `i3c_master_bus_init` function may attach the I2C devices before the
I3C bus initialization. In this flow, the DAT `alloc_entry`` will be used
before the DAT `init`. Additionally, if the `i3c_master_bus_init` fails,
the DAT `cleanup` will execute before the device is detached, which will
execue DAT `free_entry` function. The above scenario can cause the driver
to use DAT_data when it is NULL.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: i3c: master: mipi-i3c-hci: se corrigió un pánico del kernel al acceder a DAT_data. La función `i3c_master_bus_init` puede conectar los dispositivos I2C antes de la inicialización del bus I3C. En este flujo, el DAT `alloc_entry`` se utilizará antes del DAT `init`. Además, si `i3c_master_bus_init` falla, la `limpieza` de DAT se ejecutará antes de desconectar el dispositivo, lo que ejecutará la función DAT `free_entry`. El escenario anterior puede hacer que el controlador utilice DAT_data cuando es NULL.
