Descriptions

Race condition in the cm_work_handler function in the InfiniBand driver (drivers/infiniband/core/cma.c) in Linux kernel 2.6.x allows remote attackers to cause a denial of service (panic) by sending an InfiniBand request while other request handlers are still running, which triggers an invalid pointer dereference.

Condición de carrera en la función cm_work_handler del controlador InfiniBand (drivers/infiniband/core/cma.c) del kernel de Linux 2.6.x. Permite a atacantes remotos provocar una denegación de servicio (panic) enviando una petición InfiniBand mientras otros manejadores de petición se están ejecutando, lo que provoca una resolución de puntero inválida.
