CVE-2025-23136:
Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2025-23136 was discovered in the Linux kernel's thermal subsystem, specifically affecting the int340x thermal driver. The vulnerability was disclosed on April 16, 2025, and involves a potential NULL pointer dereference in the int3402thermalprobe() function (NVD, Red Hat).
Technical details
The vulnerability occurs in the thermal subsystem's int340x driver where not all devices have an ACPI companion fwnode, resulting in adev potentially being NULL. The issue is similar to a previous fix (cd2fd6eab480) for the platform/x86: int3472 component. The vulnerability has been assigned a CVSS v3.1 score of 5.5 with a vector string of CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H (Red Hat).
Impact
The vulnerability could lead to a NULL pointer dereference in the int3402thermalprobe() function, potentially causing system crashes or denial of service conditions (NVD).
Mitigation and workarounds
The vulnerability has been resolved by adding a NULL check for adev and returning -ENODEV when adev is not set. This fix has been incorporated into Linux kernel version 6.12.24 (Debian List).
