CVE-2024-42285

In the Linux kernel, the following vulnerability has been resolved: RDMA/iwcm: Fix a use-after-free related to destroying CM IDs 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.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: RDMA/iwcm: corrige un use-after-free relacionado con la destrucción de ID de CM iw_conn_req_handler() asocia una nueva estructura rdma_id_private (conn_id) con una estructura iw_cm_id (cm_id) existente de la siguiente manera: conn_id->cm_id.iw = cm_id; cm_id->context = conn_id; cm_id->cm_handler = cma_iw_handler; rdma_destroy_id() libera tanto cm_id como struct rdma_id_private. Asegúrese de que cm_work_handler() no active un use-after-free liberando solo la estructura rdma_id_private después de que todo el trabajo pendiente haya finalizado.
