CVE-2023-53811

The CVE-2023-53811 issue affects the Linux kernel’s irdma RDMA driver: the driver could allocate MSIX vectors up to num_online_cpus() + 1, and when this limit is exceeded the kernel would warn while updating CPU affinity with a mask larger than available CPUs. The fix caps MSIX vectors to num_onl...
