CVE-2023-52763

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_initfails, the DATcleanupwill execute before the device is detached, which will execue DATfree_entry` function. The above scenario can cause the driver to use DAT_data when it is NULL.
