Executive Summary

This vulnerability is a memory leak in the Linux kernel's objtool component, specifically in the create_static_call_sections() function. The issue occurs because memory allocated by strdup() for key_name is not properly freed in certain error paths. The fix involves adding free() calls to release this memory and prevent the leak.

Impact Analysis

The memory leak could lead to increased memory usage over time, potentially causing system instability or degraded performance if the leak occurs frequently or in critical environments.
