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/.
