CVE-2023-54302

EUVD-2023-60502

In the Linux kernel, the following vulnerability has been resolved:

RDMA/irdma: Fix data race on CQP completion stats

CQP completion statistics is read lockesly in irdma_wait_event and
irdma_check_cqp_progress while it can be updated in the completion
thread irdma_sc_ccq_get_cqe_info on another CPU as KCSAN reports.

Make completion statistics an atomic variable to reflect coherent updates
to it. This will also avoid load/store tearing logic bug potentially
possible by compiler optimizations.
