"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: pm8001: Fix use-after-free for aborted SSP/STP sas_task\n\nCurrently a use-after-free may occur if a sas_task is aborted by the upper\nlayer before we handle the I/O completion in mpi_ssp_completion() or\nmpi_sata_completion().\n\nIn this case, the following are the two steps in handling those I/O\ncompletions:\n\n - Call complete() to inform the upper layer handler of completion of\n the I/O.\n\n - Release driver resources associated with the sas_task in\n pm8001_ccb_task_free() call.\n\nWhen complete() is called, the upper layer may free the sas_task. As such,\nwe should not touch the associated sas_task afterwards, but we do so in the\npm8001_ccb_task_free() call.\n\nFix by swapping the complete() and pm8001_ccb_task_free() calls ordering."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: pm8001: Corrige el use-after-free para sas_task SSP/STP abortado. Actualmente, puede ocurrir un use-after-free si la capa superior cancela una sas_task antes de que manejemos el Finalizaci\u00f3n de E/S en mpi_ssp_completion() o mpi_sata_completion(). En este caso, los siguientes son los dos pasos para manejar esas finalizaciones de E/S: - Llamar a complete() para informar al controlador de la capa superior de la finalizaci\u00f3n de la E/S. - Liberar los recursos del controlador asociados con sas_task en la llamada pm8001_ccb_task_free(). Cuando se llama a complete(), la capa superior puede liberar sas_task. Como tal, no debemos tocar el sas_task asociado despu\u00e9s, pero lo hacemos en la llamada pm8001_ccb_task_free(). Se soluciona intercambiando el orden de las llamadas complete() y pm8001_ccb_task_free()."
