Description
In the Linux kernel, the following vulnerability has been resolved: mlxsw: minimal: fix potential memory leak in mlxsw_m_linecards_init The line cards array is not freed in the error path of mlxsw_m_linecards_init(), which can lead to a memory leak. Fix by freeing the array in the error path, thereby making the error path identical to mlxsw_m_linecards_fini().

Executive Summary

This vulnerability is a potential memory leak in the Linux kernel's mlxsw driver. Specifically, in the mlxsw_m_linecards_init() function, if an error occurs, the allocated line cards array is not freed properly, which can cause a memory leak. The fix involves freeing this array in the error path to prevent the leak.

Impact Analysis

The impact of this vulnerability is a potential memory leak in the Linux kernel, which could lead to increased memory usage and possibly degrade system performance or stability over time if the error path is triggered repeatedly.
