Linux Kernel NVMe-RDMA: Double Cleanup on -EIO in queue_rq
CVE-2026-98154 Published on September 25, 2026
nvme-rdma: fix -EIO cleanup order in queue_rq
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.
