Descriptions

A memory leak in the bfad_im_get_stats() function in drivers/scsi/bfa/bfad_attr.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering bfa_port_get_stats() failures, aka CID-0e62395da2bd.

Una pérdida de memoria en la función bfad_im_get_stats() en el archivo drivers/scsi/bfa/bfad_attr.c en el kernel de Linux versiones hasta la versión 5.3.11, permite a atacantes causar una denegación de servicio (consumo de memoria) al desencadenar fallos de la función de bfa_port_get_stats(), también se conoce como CID-0e62395da2bd.
