Boris Pismenny 5ecce4c9b1 RDMA/uverbs: Check port number supplied by user verbs cmds ... The ib_uverbs_create_ah() ind ib_uverbs_modify_qp() calls receive the port number from user input as part of its attributes and assumes it is valid. Down on the stack, that parameter is used to access kernel data structures. If the value is invalid, the kernel accesses memory it should not. To prevent this, verify the port number before using it.
