CVE-2023-53539 is an incomplete work queue element (WQE) state-save and restoration flaw in the Linux kernel Soft-RoCE RDMA/rxe requester path. When an IP-layer packet drop causes rxe_xmit_packet() to return -EAGAIN, rxe_requester() restores WQE state for retransmission. The affected save and restore logic omitted the DMA structure used to process the scatter-gather entry table and did not save that state before packet construction modified it. Consequently, retransmitted packets can be constructed with invalid DMA processing state.
