Overview

CVE-2026-72144 is a high-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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: dell-laptop: fix missing cleanups in init error path

dell_init() initializes several resources after dell_setup_rfkill(),

including the optional touchpad LED, keyboard backlight LED, battery

hook, debugfs directory and dell-laptop notifier.

If a later LED or backlight registration fails, the error path only

tears down the battery hook and rfkill resources. This leaves the

notifier, debugfs directory, keyboard backlight LED and optional

touchpad LED registered after dell_init() returns an error.

Add the missing cleanup calls before tearing down rfkill.

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.
