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.
