Linux kernel built with the InfiniBand communication link(CONFIG_INFINIBAND)
along with the support for Remote Direct Memory Access(RDMA) over Convered
Ethernet(RoCE), is vulnerable to a crash caused by invalid memory access.
It occurs while trying to resolve RoCE L2 address on the server side.
A remote unprivileged user/program could use this flaw to crash the kernel,
resulting in DoS.
Issue introduced by commit:
This issue does not affect the versions of the kernel package as shipped with
Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG 2.
