CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Linux Kernel up to 6.6.147/6.12.96/6.18.39/7.1.4 and classified as problematic. Affected by this issue is the function dell_init of the component dell-laptop. The manipulation with an unknown input leads to a initialization vulnerability. Using CWE to declare the problem leads to CWE-665. The product does not initialize or incorrectly initializes a resource, which might leave the resource in an unexpected state when it is accessed or used. Impacted is availability. CVE summarizes:

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.

The advisory is available at git.kernel.org. This vulnerability is handled as CVE-2026-72144 since 08/09/2026. The exploitation is known to be easy. Local access is required to approach this attack. The exploitation requires an enhanced level of successful authentication. Technical details are known, but there is no available exploit.

Upgrading to version 6.6.148, 6.12.97, 6.18.40, 7.1.5 or 7.2-rc1 eliminates this vulnerability. Applying the patch e4908b3bed755f73870416b971e162a8d0ef0aef/6bd76d5421a72d2526c9be8f01f55bee960f899f/1e41ca4a7fba2e680d6950e9511245255fffa46c/b351e082711d12f075a36a6cd67709693689315f/6e9cab2247e5b243ae2d907ce7c948a8a9c8d61a is able to eliminate this problem.
