CVE-2022-48791

In the Linux kernel, the following vulnerability has been resolved: scsi: pm8001: Fix use-after-free for aborted TMF sas_task Currently a use-after-free may occur if a TMF sas_task is aborted before we handle the IO completion in mpi_ssp_completion(). The abort occurs due to timeout. When the timeout occurs, the SAS_TASK_STATE_ABORTED flag is set and the sas_task is freed in pm8001_exec_internal_tmf_task(). However, if the I/O completion occurs later, the I/O completion still thinks that the sas_task is available. Fix this by clearing the ccb->task if the TMF times out - the I/O completion handler does nothing if this pointer is cleared.

Summary		(es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: scsi: pm8001: Corrección 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 finalización 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 finalización de E/S se produce más tarde, la finalización de E/S todavía piensa que sas_task está disponible. Solucione este problema borrando la tarea ccb-> si se agota el tiempo de espera del TMF; el controlador de finalización de E/S no hace nada si se borra este puntero.
