From this webpage screenshot, the following key information about the vulnerability can be obtained: Vulnerability Type: Soft lockup. Affected Component: RDMA/hns driver, specifically during allocation and mapping of bt pages. Issue Description: When allocating large buffers (e.g., MRs exceeding 100GB), the loop count may become extremely large, leading to a soft lockup. Specific Error Messages: - - Fix: Added calls within these loops to resolve the soft lockup. To avoid impacting performance for normal-sized buffer allocations, a threshold of 100GB MR is used to trigger .
