CVE-2014-8159: Integer Overflow

First published: Mon Jan 12 2015(Updated: )

It was found that the Linux kernel's Infiniband subsystem did not properly sanitize input parameters while registering memory regions from the userspace via the (u)verbs API. As a result, an unrestricted physical memory access could be achieved. A local user with access to /dev/infiniband/uverbsX could use this flaw to crash the system or, potentially, escalate their privileges on the system.
