Linux Kernel vulnerability analysis and mitigation
Overview
In the Linux kernel, a vulnerability (CVE-2025-38705) was discovered in the drm/amd/pm component. The issue was disclosed on September 4, 2025. The vulnerability occurs when writing a string without delimiters (' ', '\n', '\0') to the gpu_od/fan_ctrl sysfs or pp_power_profile_mode for the CUSTOM profile, which can result in a null pointer dereference (NVD).
Technical details
The vulnerability is related to null pointer access in the AMD Power Management (PM) component of the Direct Rendering Manager (DRM) subsystem. The issue specifically manifests when handling string inputs without proper delimiters in the gpu_od/fan_ctrl sysfs interface or when setting the pp_power_profile_mode for CUSTOM profiles (NVD).
Impact
When exploited, this vulnerability leads to a null pointer dereference in the Linux kernel, which could potentially cause a system crash or denial of service condition (NVD).
Mitigation and workarounds
The vulnerability has been resolved in the Linux kernel through a patch that fixes the null pointer access issue in the drm/amd/pm component (NVD).
