Overview

CVE-2026-31565 is a medium-severity vulnerability. It was published on April 24, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

RDMA/irdma: Fix deadlock during netdev reset with active connections

Resolve deadlock that occurs when user executes netdev reset while RDMA

applications (e.g., rping) are active. The netdev reset causes ice

driver to remove irdma auxiliary driver, triggering device_delete and

subsequent client removal. During client removal, uverbs_client waits

for QP reference count to reach zero while cma_client holds the final

reference, creating circular dependency and indefinite wait in iWARP

mode. Skip QP reference count wait during device reset to prevent

deadlock.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
