DEBIAN-CVE-2023-54302

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 irdmawaitevent and irdmacheckcqpprogress while it can be updated in the completion thread irdmascccqgetcqeinfo 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.
