Received Received - Intake
Memory Leak in Linux Kernel pinctrl pinconf-generic Component

Publication date: 2026-03-25

Last updated on: 2026-04-23

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: pinctrl: pinconf-generic: Fix memory leak in pinconf_generic_parse_dt_config() In pinconf_generic_parse_dt_config(), if parse_dt_cfg() fails, it returns directly. This bypasses the cleanup logic and results in a memory leak of the cfg buffer. Fix this by jumping to the out label on failure, ensuring kfree(cfg) is called before returning.

Executive Summary

This vulnerability is a memory leak in the Linux kernel's pinctrl subsystem, specifically in the pinconf-generic component. The issue occurs in the function pinconf_generic_parse_dt_config(), where if the helper function parse_dt_cfg() fails, the code returns immediately without executing the cleanup logic. This causes the allocated memory buffer (cfg) to not be freed, resulting in a memory leak.

Impact Analysis

The impact of this vulnerability is a memory leak in the Linux kernel. Over time, repeated triggering of this issue could cause increased memory usage, potentially leading to reduced system performance or stability issues. However, there is no indication of direct exploitation beyond the memory leak itself.
