  "title": "linux: In the Linux kernel, the following vulnerability has been resolved:  i3c: master: svc: Fix use after free vulnerabili...",
  "description": "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, \u0026master-\u003Ehj_work is bound with svc_i3c_master_hj_work, \u0026master-\u003Eibi_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-\u003Ebase 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(\u0026master-\u003Ebase)| device_unregister(\u0026master-\u003Edev)     | device_release                      | //free master-\u003Ebase                 |                                     | i3c_master_do_daa(\u0026master-\u003Ebase)                                     | //use master-\u003Ebase  Fix it by ensuring that the work is canceled before proceeding with the cleanup in svc_i3c_master_remove.",
