Details

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().

Severity ?

5.5 (Medium)
