Description
In the Linux kernel, the following vulnerability has been resolved: clk: imx: clk-imx8mn: fix memory leak in imx8mn_clocks_probe Use devm_of_iomap() instead of of_iomap() to automatically handle the unused ioremap region. If any error occurs, regions allocated by kzalloc() will leak, but using devm_kzalloc() instead will automatically free the memory using devm_kfree().

Executive Summary

This vulnerability is a memory leak issue in the Linux kernel's clk-imx8mn driver. The problem occurs because the code uses of_iomap() and kzalloc() which do not automatically free allocated memory if an error happens. The fix involves using devm_of_iomap() and devm_kzalloc(), which automatically manage and free memory, preventing leaks.

Impact Analysis

The memory leak caused by this vulnerability can lead to increased memory usage and potential resource exhaustion on affected systems, which may degrade system performance or cause instability over time.
