Linux Kernel up to 7.1.4 hwmon atk_ec_present out-of-bounds

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.

Performing a manipulation results in out-of-bounds. This vulnerability is identified as CVE-2026-80593. The attack is only possible with local access. There is not any exploit available.

Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel up to 7.1.4. This affects the function atk_ec_present of the component hwmon. The manipulation with an unknown input leads to a out-of-bounds vulnerability. CWE is classifying the issue as CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: hwmon: (asus_atk0110) Check package count before accessing element atk_ec_present() walks the management group package returned by the GGRP ACPI method and, for each sub-package, reads its first element: id = &obj->package.elements[0]; if (id->type != ACPI_TYPE_INTEGER) without checking that the sub-package is non-empty. ACPICA allocates the element array with exactly package.count entries, so for a sub-package with a zero count this reads past the allocation. The sibling function atk_debugfs_ggrp_open() performs the same access but skips empty packages with a package.count check first. Add the same check to atk_ec_present() so a malformed firmware package cannot trigger an out-of-bounds read.

It is possible to read the advisory at git.kernel.org. This vulnerability is uniquely identified as CVE-2026-80593 since 08/26/2026. The exploitability is told to be easy. Attacking locally is a requirement. Technical details of the vulnerability are known, but there is no available exploit.

Upgrading to version 5.10.261, 5.15.212, 6.1.178, 6.6.145, 6.12.97, 6.18.40 or 7.1.5 eliminates this vulnerability. Applying the patch 2a137124664aad1e36d8d74e8e2207365a04737f/459b0a0439ea65b2b612aa572eb62a2e26d05618/768f20e7bb48d723b82cb142120263d0806fbeb8/76392d35c8df471b288cfc6536bd092b3c8ee2cf/981a8a2e3773dc7e704943388a1fb97970b23275/d8d4fa0c4f818e30b6f6737bdd989b7e2b511cae/b770fcfcdced569bcf7c6982aeea8c3d11a21c2b/e2735b39f044bad7bf2017aef248935525bc0b97 is able to eliminate this problem.
