{"id":"DEBIAN-CVE-2023-54302","details":"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.
