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.
