Linux Kernel GPIO Aggregator Software Node Leak

Publication date: 2026-07-19

Last updated on: 2026-07-19

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: gpio: aggregator: remove the software node when deactivating the aggregator The dynamic software node we create for the aggregator platform device when using configfs is leaked when the device is deactivated. Destroy it as the last step in the tear-down path.

Executive Summary

This vulnerability in the Linux kernel involves a memory leak in the GPIO aggregator module. When a device using configfs is deactivated, the software node created for the aggregator platform device is not properly destroyed, leading to resource leakage.

Detection Guidance

This vulnerability is specific to the Linux kernel's GPIO aggregator functionality and may not have direct network detection methods. Check kernel logs for errors related to gpio aggregator or configfs using: dmesg | grep -i gpio or dmesg | grep -i configfs. Verify if the aggregator device is properly deactivated using: ls /sys/bus/platform/devices/ | grep aggregator.

Impact Analysis

This vulnerability may cause system instability or resource exhaustion over time due to the leaked software node. It could lead to performance degradation or unexpected behavior in systems using the GPIO aggregator functionality.

Compliance Impact

This vulnerability does not directly affect compliance with GDPR, HIPAA, or similar standards. It involves a memory leak in the Linux kernel's GPIO aggregator module, which could lead to resource exhaustion but does not impact data protection or privacy requirements.

Mitigation Strategies

Update your Linux kernel to the latest stable version that includes the fix for this vulnerability. If immediate update is not possible, disable the GPIO aggregator functionality by removing related kernel modules or configurations until the patch is applied.
