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 6.15.7. It has been classified as critical. This affects the function airoha_npu_get of the component net. The manipulation with an unknown input leads to a use after free vulnerability. CWE is classifying the issue as CWE-416. Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code. 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: net: airoha: fix potential use-after-free in airoha_npu_get() np->name was being used after calling of_node_put(np), which releases the node and can lead to a use-after-free bug. Previously, of_node_put(np) was called unconditionally after of_find_device_by_node(np), which could result in a use-after-free if pdev is NULL. This patch moves of_node_put(np) after the error check to ensure the node is only released after both the error and success cases are handled appropriately, preventing potential resource issues.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2025-38536 since 04/16/2025. The exploitability is told to be easy. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 01/30/2026).
