CVE-2014-8159
Published: 31 December 2014
The InfiniBand (IB) implementation in the Linux kernel package before 2.6.32-504.12.2 on Red Hat Enterprise Linux (RHEL) 6 does not properly restrict use of User Verbs for registration of memory regions, which allows local users to access arbitrary physical memory locations, and consequently cause a denial of service (system crash) or gain privileges, by leveraging permissions on a uverbs device under /dev/infiniband/.
From the Ubuntu security team
It was discovered that the Linux kernel's Infiniband subsystem did not properly sanitize its input parameters while registering memory regions from userspace. A local user could exploit this flaw to cause a denial of service (system crash) or to potentially gain administrative privileges.
