  "details": "In the Linux kernel, the following vulnerability has been resolved:  i3c: master: Fix use-after-free of master-\u003ethis  sysfs attribute callbacks for the master controller device dereference master-\u003ethis.  However, master-\u003ethis is freed in i3c_master_detach_free_devs() before the master device itself is released.  As a result, sysfs accesses can dereference a freed master-\u003ethis pointer, leading to a use-after-free.  Keep master-\u003ethis alive until i3c_masterdev_release(), which is called after the master device and its sysfs state are being torn down. Do not free master-\u003ethis as part of the normal device detach path.  On the error path in i3c_master_set_info(), reset master-\u003ethis and bus.cur_master to NULL before freeing the allocated device.",
