Description
In the Linux kernel, the following vulnerability has been resolved: platform/x86: think-lmi: Fix memory leak when showing current settings When retriving a item string with tlmi_setting(), the result has to be freed using kfree(). In current_value_show() however, malformed item strings are not freed, causing a memory leak. Fix this by eliminating the early return responsible for this.

Executive Summary

This vulnerability is a memory leak in the Linux kernel's think-lmi component on the x86 platform. Specifically, when retrieving an item string with the function tlmi_setting(), the returned string must be freed using kfree(). However, in the current_value_show() function, malformed item strings were not freed properly due to an early return, causing a memory leak. The fix involved removing this early return to ensure all allocated memory is freed correctly.

Impact Analysis

The memory leak caused by this vulnerability can lead to increased memory usage over time, potentially degrading system performance or causing resource exhaustion. This could affect system stability, especially on systems that frequently use the think-lmi component to show current settings.
