CVE-2011-0695

Published: 15 March 2011

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.

From the Ubuntu security team

Jens Kuehnel discovered that the InfiniBand driver contained a race condition. On systems using InfiniBand, a local attacker could send specially crafted requests to crash the system, leading to a denial of service.
