Description
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: fix memory leak in mlx5e_fs_tt_redirect_any_create The memory pointed to by the fs->any pointer is not freed in the error path of mlx5e_fs_tt_redirect_any_create, which can lead to a memory leak. Fix by freeing the memory in the error path, thereby making the error path identical to mlx5e_fs_tt_redirect_any_destroy().

Executive Summary

This vulnerability is a memory leak in the Linux kernel's mlx5e network driver. Specifically, the memory pointed to by the fs->any pointer is not freed in the error path of the function mlx5e_fs_tt_redirect_any_create. This means that if an error occurs during this function, allocated memory is not properly released, leading to a memory leak. The fix involves freeing this memory in the error path to prevent the leak.

Impact Analysis

The memory leak can cause increased memory usage over time, potentially leading to degraded system performance or instability if the leak accumulates. In systems using the affected Linux kernel network driver, this could result in resource exhaustion or crashes under certain conditions.
