CVE-2011-0695: Canonical Ubuntu Linux

Medium severity, CVSS 5.7. EPSS: 1.2% chance of exploitation in the next 30 days.

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.

• Linux Linux Kernel: from 2.6.0, up to and including 2.6.39.4
• Red Hat Enterprise Linux Desktop: version 5.0 only
