Linux Kernel up to 6.2.4 thermal alloc_soc_dts null pointer dereference

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, which was classified as critical, was found in Linux Kernel up to 6.2.4. Affected is the function alloc_soc_dts of the component thermal. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: thermal: intel: quark_dts: fix error pointer dereference If alloc_soc_dts() fails, then we can just return. Trying to free "soc_dts" will lead to an Oops.

The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2023-54298 since 12/30/2025. There are known technical details, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 281479 (Linux Distros Unpatched Vulnerability : CVE-2023-54298), which helps to determine the existence of the flaw in a target environment.
