CVE-2025-38211 is a slab use-after-free in the Linux kernel RDMA iWARP Connection Manager (RDMA/iWCM). Work entries are allocated for each cm_id_private object during cm_id creation and are released when the final cm_id reference is dropped. An event-handler work item can drop that final reference, causing dealloc_work_entries() to free the work object that is still executing or remains accessible to the iWCM workqueue. KASAN detects the resulting access in workqueue activation. The flaw remained after an earlier fix that flushed pending work during cm_id destruction, because that fix did not prevent the final dereference from occurring in an event-handler work context.
