| Doc Text: |
A race condition was identified in the RDMA/irdma subsystem of the Linux kernel affecting how completion queue pair (CQP) requests are processed. The cqp_request->request_done memory location is accessed without appropriate synchronization in the irdma_handle_cqp_op function while it is concurrently updated in irdma_cqp_ce_handler. Kernel Concurrency Sanitizer can detect this unsafe access pattern, which may lead to unpredictable behavior, kernel warnings, or system instability
