Publication date: 2026-06-24

Last updated on: 2026-06-24

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: sti: use managed regmap_field allocations The regmap_field objects allocated at player init are never freed and may leak resources if the driver is removed. Switch to devm_regmap_field_alloc() to automatically limit the lifetime of the allocations the lifetime of the device.

Executive Summary

This vulnerability exists in the Linux kernel's ASoC sti driver where regmap_field objects allocated during player initialization are not freed properly.

Because these objects are never freed, they may cause resource leaks if the driver is removed.

The fix involves switching to devm_regmap_field_alloc(), which manages the lifetime of these allocations automatically, tying them to the lifetime of the device.

Impact Analysis

The vulnerability can lead to resource leaks in the system when the affected driver is removed.

Resource leaks may degrade system performance or stability over time if resources are not properly released.

Mitigation Strategies

The vulnerability involves resource leaks due to regmap_field objects not being freed when the driver is removed.

To mitigate this issue, update the Linux kernel to a version where the ASoC sti driver uses devm_regmap_field_alloc() instead of manual allocations. This change ensures that the lifetime of the allocations is automatically managed and limited to the device's lifetime.
