La función iscsi_if_rx en drivers/scsi/scsi_transport_iscsi.c en el kernel de Linux hasta la versión 4.13.2 permite que usuarios locales provoquen una denegación de servicio (pánico) aprovechando que se realiza una validación de longitud incorrecta.

Anthony Perard discovered that the Xen virtual block driver did not properly initialize some data structures before passing them to user space. A local attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs. Bo Zhang discovered that the netlink wireless configuration interface in the Linux kernel did not properly validate attributes when handling certain requests. A local attacker with the CAP_NET_ADMIN could use this to cause a denial of service. Various other issues were also addressed.
