Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2025-37841 is a vulnerability discovered in the Linux kernel affecting the cpupower benchmarking component. The vulnerability was disclosed on May 9, 2025, and involves a potential NULL pointer dereference in the power management subsystem (Wiz Report).
Technical details
The vulnerability occurs in the Linux kernel's power management subsystem, specifically in the cpupower benchmarking functionality. The issue arises when malloc returns NULL due to low memory conditions, causing the 'config' pointer to be NULL without proper validation. This could lead to a NULL pointer dereference (Debian Tracker).
Impact
The vulnerability has been assessed with a CVSS v3.1 Base Score of 5.5, indicating moderate severity. The vulnerability requires local access and low attack complexity to exploit (Wiz Report).
Mitigation and workarounds
The vulnerability has been fixed in various Linux kernel versions. Debian has addressed the issue in version 6.1.135-1 for the bookworm release and version 6.12.25-1 for the trixie release. The fix involves adding a check to prevent NULL pointer dereference when malloc fails (Debian Tracker).
