  "description": "In the Linux kernel, the following vulnerability has been resolved:  scsi: libsas: Fix use-after-free bug in smp_execute_task_sg()  When executing SMP task failed, the smp_execute_task_sg() calls del_timer() to delete \u0022slow_task-\u003Etimer\u0022. However, if the timer handler sas_task_internal_timedout() is running, the del_timer() in smp_execute_task_sg() will not stop it and a UAF will happen. The process is shown below:        (thread 1)               |        (thread 2) smp_execute_task_sg()          | sas_task_internal_timedout()  ...                           |  del_timer()                   |  ...                           |  ...  sas_free_task(task)           |   kfree(task-\u003Eslow_task) //FREE|                                |  task-\u003Eslow_task-\u003E... //USE  Fix by calling del_timer_sync() in smp_execute_task_sg(), which makes sure the timer handler have finished before the \u0022task-\u003Eslow_task\u0022 is deallocated.",
