Overview

CVE-2025-71313 is a medium-severity vulnerability. It was published on June 3, 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:

PCI: endpoint: Add missing NULL check for alloc_workqueue()

alloc_workqueue() can return NULL on memory allocation failure. Without

proper error checking, this may lead to a NULL pointer dereference when

queue_work() is later called with the NULL workqueue pointer in

epf_ntb_epc_init().

Add a NULL check immediately after alloc_workqueue() and return -ENOMEM on

failure to prevent the driver from loading with an invalid workqueue

pointer.

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.
