"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: pm8001: Fix use-after-free for aborted TMF sas_task\n\nCurrently a use-after-free may occur if a TMF sas_task is aborted before we\nhandle the IO completion in mpi_ssp_completion(). The abort occurs due to\ntimeout.\n\nWhen the timeout occurs, the SAS_TASK_STATE_ABORTED flag is set and the\nsas_task is freed in pm8001_exec_internal_tmf_task().\n\nHowever, if the I/O completion occurs later, the I/O completion still\nthinks that the sas_task is available. Fix this by clearing the ccb->task\nif the TMF times out - the I/O completion handler does nothing if this\npointer is cleared."

"value": "En el kernel de Linux, se resolvi\u00f3 la siguiente vulnerabilidad: scsi: pm8001: Correcci\u00f3n de use-after-free para TMF sas_task abortada Actualmente, puede ocurrir un use-after-free si se cancela una TMF sas_task antes de que manejemos la finalizaci\u00f3n de IO en mpi_ssp_completion( ). El aborto se produce debido al tiempo de espera. Cuando se agota el tiempo de espera, se establece el indicador SAS_TASK_STATE_ABORTED y sas_task se libera en pm8001_exec_internal_tmf_task(). Sin embargo, si la finalizaci\u00f3n de E/S se produce m\u00e1s tarde, la finalizaci\u00f3n de E/S todav\u00eda piensa que sas_task est\u00e1 disponible. Solucione este problema borrando la tarea ccb-> si se agota el tiempo de espera del TMF; el controlador de finalizaci\u00f3n de E/S no hace nada si se borra este puntero."
