Description
In the Linux kernel, the following vulnerability has been resolved: pinctrl: thunderbay: fix possible memory leak in thunderbay_build_functions() The thunderbay_add_functions() will free memory of thunderbay_funcs when everything is ok, but thunderbay_funcs will not be freed when thunderbay_add_functions() fails, then there will be a memory leak, so we need to add kfree() when thunderbay_add_functions() fails to fix it. In addition, doing some cleaner works, moving kfree(funcs) from thunderbay_add_functions() to thunderbay_build_functions().

Executive Summary

This vulnerability is a memory leak in the Linux kernel's thunderbay pinctrl driver. Specifically, when the function thunderbay_add_functions() fails, it does not free the allocated memory for thunderbay_funcs, causing a memory leak. The fix involves adding a kfree() call to free this memory upon failure and reorganizing the code to better manage memory cleanup.

Impact Analysis

The memory leak caused by this vulnerability can lead to increased memory usage over time, potentially degrading system performance or causing instability if the leaked memory accumulates significantly.
