Descriptions

The Reliable Datagram Sockets (RDS) subsystem in the Linux kernel before 2.6.38 does not properly handle congestion map updates, which allows local users to cause a denial of service (BUG_ON and system crash) via vectors involving (1) a loopback (aka loop) transmit operation or (2) an InfiniBand (aka ib) transmit operation.

El subsistema 'Reliable Datagram Sockets' (SDR) del kernel de Linux en versiones anteriores a v2.6.38 no gestiona correctamente las actualizaciones del mapa de congestiones, lo que permite a usuarios locales causar una denegación de servicio (caída del sistema) a través de vectores relacionados con (1) una opeeración de transmisión 'loopback' (loop) o (2) una operación de transmisión 'InfiniBand' (ib).
