Not scored yetLast modified Oct 21, 2026

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.
