In the Linux kernel, the following vulnerability has been resolved:
ntfs: free volume-wide resources on fill_super failure
ntfs_fill_super()'s err_out_now path frees only the volume struct via kfree(vol), leaving several vol-owned allocations behind on every mount failure:
-
vol->nls_map, loaded by ntfs_init_fs_context() via load_nls_default() (or replaced by an explicit nls= option in ntfs_parse_param()), is never unload_nls()'d.
-
vol->volume_label, allocated by load_system_files() through ntfs_ucstonls() once the $Volume name attribute has been parsed, is not released by load_system_files()'s own error labels nor by the fill_super() inline cleanup that only runs on d_make_root() failure. Any later failure inside load_system_files() leaks it.
-
vol->lcn_empty_bits_per_page was kvfree()'d in unl_upcase_iput_tmp_ino_err_out_now without clearing the pointer, so it could not be folded into a single common cleanup.
