# CVE-2025-23136

## Summary

- **CVE ID:** CVE-2025-23136
- **Severity:** MEDIUM
- **CVSS Score:** 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
- **CWE:** N/A
- **Published:** Apr 16, 2025

## Description

In the Linux kernel, the following vulnerability has been resolved:

thermal: int340x: Add NULL check for adev

Not all devices have an ACPI companion fwnode, so adev might be NULL.
This is similar to the commit cd2fd6eab480
("platform/x86: int3472: Check for adev == NULL").

Add a check for adev not being set and return -ENODEV in that case to
avoid a possible NULL pointer deref in int3402_thermal_probe().

Note, under the same directory, int3400_thermal_probe() has such a
check.
