Description

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).
