Summary
i3c: master: svc: Fix use after free vulnerability in svc_i3c_master Driver Due to Race Condition
Details

In the Linux kernel, the following vulnerability has been resolved:

i3c: master: svc: Fix use after free vulnerability in svc_i3c_master Driver Due to Race Condition

In the svc_i3c_master_probe function, &master->hj_work is bound with svc_i3c_master_hj_work, &master->ibi_work is bound with svc_i3c_master_ibi_work. And svc_i3c_master_ibi_work can start the hj_work, svc_i3c_master_irq_handler can start the ibi_work.

If we remove the module which will call svc_i3c_master_remove to make cleanup, it will free master->base through i3c_master_unregister while the work mentioned above will be used. The sequence of operations that may lead to a UAF bug is as follows:

CPU0 CPU1

                                | svc_i3c_master_hj_work

svc_i3c_master_remove | i3c_master_unregister(&master->base)| device_unregister(&master->dev) | device_release | //free master->base | | i3c_master_do_daa(&master->base) | //use master->base

Fix it by ensuring that the work is canceled before proceeding with the cleanup in svc_i3c_master_remove.
