Overview

CVE-2025-71114 is a medium-severity vulnerability. It was published on January 14, 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:

via_wdt: fix critical boot hang due to unnamed resource allocation

The VIA watchdog driver uses allocate_resource() to reserve a MMIO

region for the watchdog control register. However, the allocated

resource was not given a name, which causes the kernel resource tree

to contain an entry marked as "<BAD>" under /proc/iomem on x86

platforms.

During boot, this unnamed resource can lead to a critical hang because

subsequent resource lookups and conflict checks fail to handle the

invalid entry properly.

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.
