Executive Summary

This vulnerability exists in the Linux kernel's fbdev au1200fb driver, specifically in the function au1200fb_drv_probe().

When the function platform_get_irq fails, it returns immediately with an error code without properly cleaning up allocated memory, causing a memory leak.

The fix replaces the direct return with a goto label to ensure that all allocated resources are properly freed before exiting the function.

Impact Analysis

The memory leak caused by this vulnerability can lead to increased memory usage over time when the affected function fails.

This may degrade system performance or stability, especially on systems that frequently encounter this error condition.
