CVE-2026-45898

A flaw was found in the Linux kernel's Remote Direct Memory Access (RDMA) Internet Wide Area RDMA Protocol (iWARP) subsystem. Incorrect work submission logic in the `iwcm` component can lead to multiple queueing of work items. This allows a work item to be processed and freed while still present in the workqueue, causing list corruption. A successful exploitation of this vulnerability can result in a kernel bug and system crash, leading to a Denial of Service (DoS).
