Descriptions

The tipc_nl_publ_dump function in net/tipc/socket.c in the Linux kernel through 4.6 does not verify socket existence, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a dumpit operation.

La función tipc_nl_publ_dump en net/tipc/socket.c en el kernel de Linux hasta la versión 4.6 no verifica la existencia del socket, lo que permite a usuarios locales provocar una denegación de servicio (referencia a puntero NULL y caída de sistema) o posiblemente tener otro impacto no especificado a través de una operación dumpit.
