Descriptions

The rds_iw_laddr_check function in net/rds/iw.c in the Linux kernel through 3.14 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a bind system call for an RDS socket on a system that lacks RDS transports.

La función rds_iw_laddr_check en net/rds/iw.c en el kernel de Linux hasta 3.14 permite a usuarios locales causar una denegación de servicio (referencia a puntero nulo y caída de sistema) o posiblemente tener otro impacto no especificado a través de una llamada de sistema bind para un socket RDS en un sistema que carece de transportes RDS.

A NULL pointer dereference flaw was found in the rds_iw_laddr_check() function in the Linux kernel's implementation of Reliable Datagram Sockets (RDS). A local, unprivileged user could use this flaw to crash the system.
