Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，以下漏洞已得到修复： nvme-rdma: 修复 queue_rq 中 -EIO 的清理顺序问题 当发生 -EIO（输入/输出错误）时，RDMA 的 queue_rq 路径会报告主机路径错误，随后仍会执行命令清理和解映射 SQE（Submission Queue Entry，提交队列条目）的 DMA。由于路径错误辅助函数会完成该请求，这导致在请求已完成之后又进行了双重清理和解映射 DMA 操作。 正确的做法是：首先解映射 SQE，然后报告主机路径错误，并跳过该路径上的外层命令清理操作。

Vulnerability Title
nvme-rdma: fix -EIO cleanup order in queue_rq
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
nvme-rdma: fix -EIO cleanup order in queue_rq
On -EIO, the RDMA queue_rq path reports a host path error and then
still cleans up the command and unmaps the SQE DMA. The path error
helper completes the request, so that is double cleanup and DMA unmap
after the request is already complete.
Unmap the SQE first, then report the host path error. Skip the outer
command cleanup on that path.
