Descriptions

The cma_req_handler function in drivers/infiniband/core/cma.c in the Linux kernel 3.14.x through 3.14.1 attempts to resolve an RDMA over Converged Ethernet (aka RoCE) address that is properly resolved within a different module, which allows remote attackers to cause a denial of service (incorrect pointer dereference and system crash) via crafted network traffic.

La función cma_req_handler en drivers/infiniband/core/cma.c en el kernel de Linux 3.14.x hasta 3.14.1 intenta resolver un RDMA sobre una dirección Converged Ethernet (también conocido como RoCE) que se resuelve debidamente dentro de un módulo diferente, lo que permite a atacantes remotos causar una denegación de servicio (referencia a puntero incorrecto y caída de sistema) a través de trafico de red manipulado.
