FKIE_CVE-2011-0695

Vulnerability from fkie_nvd - Published: 2011-03-15 17:55 - Updated: 2026-06-16 23:27
Severity
Summary
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.
