Descriptions

The sctp_init function in net/sctp/protocol.c in the Linux kernel before 4.2.3 has an incorrect sequence of protocol-initialization steps, which allows local users to cause a denial of service (panic or memory corruption) by creating SCTP sockets before all of the steps have finished.

La función sctp_init en net/sctp/protocol.c en el kernel de Linux en versiones anteriores a 4.2.3 tiene una secuencia incorrecta de pasos de inicialización de protocolo, lo que permite a usuarios locales provocar una denegación de servicio (panic o corrupción de memoria) mediante la creación de sockets SCTP antes de haber finalizado todos los pasos.

A NULL pointer dereference flaw was found in the SCTP implementation. A local user could use this flaw to cause a denial of service on the system by triggering a kernel panic when creating multiple sockets in parallel while the system did not have the SCTP module loaded.
