| CVE-2023-52763 | Date: (C)2024-05-22 (M)2024-06-07 |
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.
