Descriptions

The sctp_do_peeloff function in net/sctp/socket.c in the Linux kernel before 4.14 does not check whether the intended netns is used in a peel-off action, which allows local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via crafted system calls.

La función sctp_do_peeloff en net/sctp/socket.c en el kernel de Linux en versiones anteriores a la 4.14 no comprueba si el netns planeado se emplea en una acción peel-off, lo que permite que usuarios locales provoquen una denegación de servicio (uso de memoria previamente liberada y cierre inesperado del sistema) o, posiblemente, otro impacto sin especificar mediante llamadas del sistema manipuladas.
