linux-stable.git/drivers/infiniband, branch v4.19.321 Linux kernel stable tree RDMA/iwcm: Fix a use-after-free related to destroying CM IDs 2024-08-19T03:32:06+00:00 Bart Van Assche bvanassche@acm.org 2024-06-05T14:51:01+00:00 d91d253c87fd1efece521ff2612078a35af673c6 commit aee2424246f9f1dadc33faa78990c1e2eb7826e4 upstream. iw_conn_req_handler() associates a new struct rdma_id_private (conn_id) with an existing struct iw_cm_id (cm_id) as follows: conn_id->cm_id.iw = cm_id; cm_id->context = conn_id; cm_id->cm_handler = cma_iw_handler; rdma_destroy_id() frees both the cm_id and the struct rdma_id_private. Make sure that cm_work_handler() does not trigger a use-after-free by only freeing of the struct rdma_id_private after all pending work has finished.

commit aee2424246f9f1dadc33faa78990c1e2eb7826e4 upstream.

iw_conn_req_handler() associates a new struct rdma_id_private (conn_id) with
an existing struct iw_cm_id (cm_id) as follows:

        conn_id->cm_id.iw = cm_id;
        cm_id->context = conn_id;
        cm_id->cm_handler = cma_iw_handler;

rdma_destroy_id() frees both the cm_id and the struct rdma_id_private. Make
sure that cm_work_handler() does not trigger a use-after-free by only
freeing of the struct rdma_id_private after all pending work has finished.
