Overview

CVE-2026-23131 is a medium-severity vulnerability. It was published on February 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:

platform/x86: hp-bioscfg: Fix kobject warnings for empty attribute names

The hp-bioscfg driver attempts to register kobjects with empty names when

the HP BIOS returns attributes with empty name strings. This causes

multiple kernel warnings:

kobject: (00000000135fb5e6): attempted to be registered with empty name!

WARNING: CPU: 14 PID: 3336 at lib/kobject.c:219 kobject_add_internal+0x2eb/0x310

Add validation in hp_init_bios_buffer_attribute() to check if the

attribute name is empty after parsing it from the WMI buffer. If empty,

log a debug message and skip registration of that attribute, allowing the

module to continue processing other valid attributes.

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.
