CVE-2022-48792

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

Summary		(es) 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 Finalización 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 finalización 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 después, pero lo hacemos en la llamada pm8001_ccb_task_free(). Se soluciona intercambiando el orden de las llamadas complete() y pm8001_ccb_task_free().
