CyberRota Analysis
AI-GeneratedThe vulnerability in the Linux kernel affects the RDMA/hns component, where a failure in the hns_roce_cmd_mbox() command interface can lead to excessive error logging, potentially resulting in system crashes. This issue can disrupt system stability, particularly in environments utilizing RDMA technology. Organizations using Linux systems with RDMA capabilities should prioritize addressing this vulnerability to prevent log flooding and ensure system reliability.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix log flood after cmd_mbox failure hns_roce_cmd_mbox() is the command interface between driver and hardware. When hardware is abnormal, the unlimited error printings after hns_roce_cmd_mbox() failure will cause log flood and even system crash. Replace ibdev_err() and ibdev_warn() with their ratelimited versions in the error handling path after hns_roce_cmd_mbox() (and its wrappers hns_roce_create_hw_ctx/hns_roce_destroy_hw_ctx) fails.
