CVSS 3.1

EPSS 0.15%

Description

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().
