Linux Kernel up to 7.1.4 arm_scmi scmi_power_name_get memory corruption

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 7.1.4. It has been classified as critical. Affected is the function scmi_power_name_get of the component arm_scmi. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Fix OOB in scmi_power_name_get() scmi_power_name_get() does not validate the domain number passed by the external caller, which may lead to an out-of-bounds access. Fix this by returning "unknown" for invalid domains, like scmi_reset_name_get() does.

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2026-80649 since 08/26/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 08/28/2026).

Upgrading to version 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 01613f5e4ff6c080260615392338e92e261d109b/ca94597440fa546e56293abe9d0af6c73535d44e/30aa348494531adfb043b2e883afc0439e5fcdca/0db2bb3c948ef8b7364768554d6ab5e1544dc441/11daac2817dca75e3eabb2050bc620c29e686fcd/11bb771f3c55b4cef3879e69da4ddecd6085569c/f9ef3f66f4b18078e464b7606f9497e4dbeb9905 is able to eliminate this problem.
