CVE-2026-98154: nvme-rdma: fix -EIO cleanup order in queue_rq

Noroxi assessment

Priority: Monitor (action score 28/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.11% (FIRST EPSS).
Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
Fixed version: Linux Linux 171b993a4aed9889159df4815b6a6ba141e61975, 965804b20c0f02c1a6cf4b69c0498a79e56f97fe, a41e7fc8d244d9cfc6273051aed85b67adedbb89; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.158.1-1.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 171b993a4aed9889159df4815b6a6ba141e61975, 965804b20c0f02c1a6cf4b69c0498a79e56f97fe, a41e7fc8d244d9cfc6273051aed85b67adedbb89; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.158.1-1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
