description

Linux kernels using the rxe RDMA driver are affected by an integer-overflow error in memory-range validation. A remote peer with access to the RDMA service can trigger an out-of-bounds memory access, potentially causing a kernel crash or memory corruption.

mitigation

Install a kernel update from your distribution that includes the rxe memory-range validation correction. Until updates are available, disable the rxe RDMA driver or restrict untrusted hosts from reaching RDMA services.
