CVE-2026-74389

In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix log flood after cmdmbox failure hnsrocecmdmbox is the command interface between driver and hardware. When hardware is abnormal, the unlimited error printings after hnsrocecmdmbox failure will cause log flood and eve...

CVE-2026-74389

Summary: CVE-2026-74389 affects the Linux kernel RDMA driver for HNS (hns_roce). When hns_roce_cmd_mbox() fails, the error path could flood logs due to unlimited ibdev_err/ibdev_warn outputs, potentially leading to a system crash. The fix replaces the non-limited error prints with ratelimited ver...
